## Theory 2 – Film all possible outcomes

September 10, 2009

DB had filmed all the possible outcomes and the films were cleverly spliced together at the last minute. He said he had been working on this for a year, well that is why. It would take a year to film each ending then cut it in.

1. All 14 million? Not plausible, even in a year. When would he have time to eat, sleep, drink? Some people have said he only promised five or more, meaning he’d only need to film some 50 000 clips. But if you watch the footage carefully, this still isn’t possible without camera trickery. He walks away from the TV screen carrying a card with the actual numbers that have been drawn on it and this card has to have all six numbers on it. Nah, this isn’t what he did. Just not elegant enough. http://nicolamonaghan.blogspot.com/2009/09/how-did-he-do-it.html

2. So he filmed it 14,000,000 times? Ridiculous..

3. 16 million combinations…1 minute each? 30 years to film???

4. this seems the most logical explanation, but it just seems so long winded, even for Derren, especially as he has been quite busy with shows etc. Can not wait for FRIDAY!

5. it would take Derren Brown 26 years to film each of the 10 minute shows to have each lottery combination

6. 13,983,816 combinations. Would have to film 38’312 a day for a year, that’s 1596 an hour with no sleep. Impossible.

7. This is a nice idea, but according to my calculations, assuming he worked 24/7 and it took him 2 minutes to film each outcome, it would have taken him…

53.2 years

8. Ok, I think this is a play on the ‘System’ stunt. I think he’s pre-recorded the most probable outcomes. Clues to this are, he can’t tell you the prediction ahead of time. There is no reaction to the balls as they are drawn, then he says the bonus ball doesn’t count, but doesn’t say what it is when drawn. He writes down the numbers in numerical sequence only at the end. Lastly he makes reference to the fact that this has taken up a YEAR of his life twice.

Permutation calculator puts 7 balls at 85,900,584 possibilities. 6 balls at 13,983,816. Still too many to film in a year. However if he went for 3 balls and put in the work in probability calculations on the remainder. That would bring permutations down to 18,424 especially as expectations are set at 5 out of the 6. Working flat out, he could pre-record all of those permutations in 128 days (presuming the full ten minutes, or less with more accuracy if filming the part where he writes down the numbers at the end).

Obviously that doesn’t allow for sleeping, eating, previous commitments, etc. which would take up the remaining time within the much referenced ‘YEAR’. Finally the pre-recorded segment is merged cleverly with the live feed to produce the end result.

Ok, that’s my guess.

9. This would be similar to the racing tips, and would require the various (but not sure how many, probably too many) outcomes to be filmed and then indexed on a computer, so that as each ball came out the filter could leave only the relevant clips. That would further explain why he said ‘at least 4 or 5 numbers’ as they may have had to pick a clip at random in order to get it in on time.

10. Not possible – there are 2,118,760 possible endings that get five balls right, and he got six. It would take far longer than a year to film them all.

11. No. He promised to get five out of six balls correct. That means he would only have to film 55 thousand or so combinations. At a minute each (the length of the sequence from the last ball being drawn) it could be filmed in a year, or even in six months if you were filming ten hours a day.

12. This is easily my favourite stupidest idea ever.

There are, I think, 49*48*47*46*45*44 possible combinations of 6 balls from 1-49. That’s 10,068,347,520 combinations. Let’s call it 10 million. And let’s say you only had to film the last 2 minutes of the broadcast, and the rest was live. That’s 20 million minutes of footage to cover all possibilities.

Regardless of where you’d store all that video, if you filmed, none stop, to get every possible outcome, 20 million minutes is 13889 days. Or a little under 40 years.

13. there are 13,983,816 different combinations.

the clip that would be prefilmed lasts 44 seconds.

this means that he would have to record 170,913 hours of footage.

if you allow the 1 minute for writing the new combination on the balls and card, and another minute to reset, thats 637,040 hours.

if he worked on this for 12 hours a day it would take 145 years.

does that seem likely?

14. Even just trying to get 4 correct numbers would take over 15 years to film all the possible outcomes. And that’s if you don’t stop for sandwiches.

15. He only claimed “at least 5 of the 6” so he would only have to record just over 15000 versions. Still a huge number but probably doable in a year.

16. My problem with this is that a person changes appearance quite a bit over a year – there’s no way you could cut in footage of derren filmed 4 months ago and not have his hair, beard, ect exactly the same.

They’d have to film the entire sequence for this to work, not just the ‘reveal’

17. The technology required to hold this amount of footage and make it accessible quick enough, probably rules out this – never mind the amount of time!

18. Good theory but only problem is that derren did this same trick with tossing a coin with the same outcome like heads a load of times in a row on one of his programmes. I cant imagine he would recycle material on such a big staged event.

19. to get 5 balls right he’s only need to film about 55000 different edits not 14 million

do the maths

20. Nope. No matter how many of the numbers he got correct on the balls, the card that he was carrying in his hand to compare to them had to have all six correct numbers on it. ie He would have to film a clip for each possible lottery combo anyway, or use some split screen jiggery pokery, in which case why pre-record anything?

Think about it this way. If he had got five numbers correct on the balls instead of six, the card in his hand still had to have the correct six numbers that we’d just seen drawn out, so that we could see he’d got five out of six and the card matched with the draw we’d just seen him watching. ie the only way to do this would be by filming all 14 million permutations of 6 choices 1 – 49….

21. even if you only account for 5 balls, not 6, its 1,906,884 clips.

with the figures i gave on my last post, it’d still take about 20 years.

or with four balls, still over 2 years.

If he did film all possible outcomes of 4 and leave the other 2 to chance, it’s take (conservatively) 2 years, or more realistically, about 4 or 5. plus, there’s only a 1 in 2401 chance that he’d get the other 2.

22. If there were 3 numbers there are 6 possible outcomes. 123 132 213 231 312 321, he would only have to film 1 piece to cover this 3 number example because he did not take into account the order of drawing the numbers. So if you apply this to the lottery numbers actually drawn, he would only have to film one piece for the numbers that were drawn. Dunno how many bits of film this would be, still loads though, but probably achievable in a year. It would involve putting a cut into the live program though, which is not too clever!
I guess he had this studio permanently set up (at his house?) so he can just drop in and do some?!

23. David said:
“That would bring permutations down to 18,424 especially as expectations are set at 5 out of the 6. Working flat out, he could pre-record all of those permutations in 128 days (presuming the full ten minutes, or less with more accuracy if filming the part where he writes down the numbers at the end).”

How would he do the show if he only got 3 right? If all his pre-recorded segments had him saying he had won, it wouldn’t work. Unless he also recorded him saying “ah well, i got these three correct anyway”. To do all the different combinations it would take even longer than just doing all of them.

24. Lets be honest…this is impossible

25. He hypnotised millions of people into believing they were Derren Brown and had them suitably made up to look like him, and then he shot the footage with them rather than himself. Obviously.

26. There’s an almost infinite number of combinations, it would take a ridiculous amount of time to film all possible combinations… would a year be enough? (I know there’s not literally an infinite number, was simply exaggerating to highlight the massive number of permutations.)
This idea was no doubt inspired by DBs show, “the system”…

27. Probably the most guaranteed way to get it done, but probably the most ridiculous. Don’t believe it was done this way – especially not with the time it would have taken and all the shows etc… that Derren has been doing the past year!

28. This is so not clever enough to be a plausible system. Anyone in the world who took enough time could make it happen this way, there is no ingenuity involved. Just a whole lot of time and effort. If this is the method explained on friday it will be the biggest anti-climax in TV history. Even worse than the Friends finale.

As for the comment about being told the numbers by Camelot, that’s even more crazy. The meeting was probably days or weeks before, and probably very necessary as there are so many legal things to talk about with regards to using BBC footage etc. I don’t think they would be allowed to just tell Derren & co the winning numbers. What would they benefit from it, anyway?
silly.

Even 55000 edits is far too many. Even if it is theoretically possible, it’s far too laborious and dull. And besides, he’s already done something like this.

I think the filming was far too seamless. If a particular iteration were spliced into the broadcast once the numbers came up there would be some kind of stutter at least. I would have thought.

It’s just not Derren, is it? The coin toss thing was proving a profound point about looking at the whole picture. He doesn’t need to make that point again, and he’s making too big a deal about this to just be repeating himself. I have a feeling the real answer hasn’t been put forward yet – something either brilliantly counterintuitive or brilliantly simple.

30. in fact, none of these theories about him only using 3, 4 or 5 balls are possible. in the clip that would potentially be prefilmed, he says that he got ALL of them right. if the idea would be to film all possible combinations to get 5 right, it wouldnt then make sense if at the end he said that he got them ALL, while showing the card, but one of them was different.

i hope i made that clear, its a hartd point to articulate.

31. His goal was 5 numbers which means around 50,000 endings. But if you play the odds, you can bring this down even more. For example it is probable that the highest number is not between 1 and 25 and the lowest number is not between 25 and 49, therefore sequences like 1,2,3,4,5,6 can be eliminated on probability. This will cut the odds down. There are computer programs that can do this. But probability is risky. Derren could always say 5 numbers is a good total even if the last number didn’t come up.
The shakey camera was definately there to cover up a live/recorded join. And he was very still for the crucial join.

32. As has been pointed out this would be impossible to do – even if you did only allow for 5 correct guesses. Of course he had to have all six guesses correct if he pre-recorded because he’s written the winning lotto numbers down so all 6 of those numbers must match the lotto.

33. · The Jackpot – 6 Numbers
6 numbers are drawn at random from the set of integers between 1 and 49, which means there are 49!/(6!*(49-6)!) combinations of numbers (the draw order doesn’t matter). The means that the jackpot chance is 1 in 13,983,816 or approximately 1 in 14 million.
· 5 Numbers + Bonus Number
You are still matching 6 numbers from the 1 to 49 set as above, but you can now do it in 6 different ways (by dropping each of the main numbers in turn), therefore the chance is 1 in 13,983,816/6, which works out as 1 in 2,330,636.
· 5 Numbers
This is 42 times more likely than getting 5 numbers + the bonus number because, after the first six balls are drawn, there are 43 balls left and you can match 42 of these 43 balls without matching the bonus number. Therefore the chance is 1 in 2,330,636/42, which evaluates to 1 in 55,491.33333.

Let’s assume that Derren Brown records a minute of footage (even though it is actually 43/44 seconds)

Predicting 6 numbers:

13,983,816 minutes of recorded TV. 13,983,816/60/24/365 = 26.60543379 years.

Predicting 5 numbers:

55,491 minutes of recorded TV. 55,491/60/24/365 = 0.105576484 years

0.105576484*52 (approx weeks in a year) = 5.489977169 weeks of solid recording/total recording over the year.

It just so happens that one of the recordings that he made with 5 of the 6 numbers from last night also contained the 6th number – something he could not guarantee but must have been quite happy about, especially as it throws you from the fact that he is only predicting 5 therefore making the maths seems impossible. It is something like 2.5hrs of filming a day for a year. Time consuming but well worth it.

On the above link you can watch the show. At 5.14 the video changes from a live feed to a pre-recorded 44 seconds of footage. The switch is extremely well practiced and shows the level of detail that has gone into the pre-recorded footage and indeed the live show.

This is just theory and no doubt he will prove me wrong on Friday.

If we work that it is 44 seconds. 55,491*(44/60) = 40,693.4

40,693.4/60/24/365 = 0.0774227549 years + 52 = 4.025983257 weeks or approximately 1.858 hours of recording a day over the course of a year.

34. This is the most illogical explanation ever. Why on earth would he bother? And he’s had 4 other shows to prepare.

By the way, someone above mentioned that “sequences like 1,2,3,4,5,6 can be eliminated on probability”. Clearly you know nothing about probability. You’re just as likely to win the lottery with 1,2,3,4,5,6 as you are with any other set of numbers.

There is a 1 in 55000(ish) chance of getting 5 numbers right, but we all know that we can fully expect Derren to get it completely right every time. Filming 14 million sequences is not faesible.

35. Quite sure he did film it. Look at previous episodes he has done and the one with the horse racing/betting. That was filmed millions of times and spliced together so we only saw the winners. He only needed to film a very small part of it again and again, and not the whole thing. That is why it has taken him a year to work on. He can’t predict the numbers …. he is an illusionist and this is the most obvious solution bearing in mind his previous work.

36. re: Stephen Jones

“in fact, none of these theories about him only using 3, 4 or 5 balls are possible. in the clip that would potentially be prefilmed, he says that he got ALL of them right. if the idea would be to film all possible combinations to get 5 right, it wouldnt then make sense if at the end he said that he got them ALL, while showing the card, but one of them was different.”

the only way that this could work is using all 6 numbers and you already admitted that that was impossible.

37. Agree totally with Stephen Jones above – the comment by Matt, although correct in his assertion about the probabilities loses it a bit when he states that it’s illogical for Derren to do a couple of hours filming a day. Remember for the system he spent about 12 hours (?) non stop flipping a coin ten times just to get 10 heads (or tails, can’t remember) in a row. Why wouldn’t he go way out for something as incredible as predicting the lottery?

The maths makes sense, and would need about 40 mins (1 hr show – adverts) to explain it in a way that his entire audience understood (ie those who aren’t particularly good at maths etc)

38. Looking back at the video again I’ve noticed a couple of things. Wasn’t too convinced that at 5.14 the feed switches to a pre-recorded one, but see if you agree with this:
1. pause it at about 5.12 and look at the white shadow of the card on the TV when it’s turned off – the white seems to disappear ever so slightly before Derren turns it all the way – try watching it in slo-mo if possible.
2. Look at his footwork – he steps with his left foot, then at 5.14 brings his legs together before stepping off with his left foot again. If I was walking straight from one point to another I wouldn’t bring one foot to the other and then walk off using the same leading foot… take a look and see what you think?

39. Another thing while I’m thinking about it still – Derren states (at about 1:40 into the youtube vid from the e4 channel) that the BBC have the legal rights to announce the lottery results first and explains that this is why he can’t show us his prediction of numbers. BUT, that doesn’t hold any weight because all he’s doing is showing us 6 numbers he predicts to win, nothing more. He wouldn’t be announcing the results if he showed us the balls at the start of the programme because it’s not the results, just his PREDICTION. If they happen to be right then shows he predicted correctly. In any case his justification for not showing us his balls (!) prior to the BBC feed is wrong. This supports the theory that there’s something that happens following the official result: something with the balls or the theory as above

40. I love all the calculations here and that they are so different; I don’t even want to work them out myself and spoil the fun! Clearly Niki and Stephen are saying some very smart things, even though they disagree with each other 😉

Suspicious, unaccounted for factors:
(1) the shaky camera – obviously not necessary in this day-and-age (and D was standing still for most of the broadcast, so no need to have free-held camera)
(2) the ‘oh I’m so nervous I hope this works do forgive me if it doesn’t’ blarney – he’s laying it on with a spade (by a man who can calmly shoot himself in the head) so this is covering something up
(3) the fact that he’s told us he’s definitely going to show us how it was done – we’re taking for granted the fact he will follow through on this, but I’m not convinced he will, thereby hyping the puzzle even further!

I can’t exactly see the join on the wobbly YouTube film, though it seems plausible, so I’m back off to watch it on my HDD from last night to see if I can spot it.

41. PS No-one’s talked about here (though it would be doable) how they patched in the live feed from the BBC onto DB’s TV screen during the pre-recorded segment while he commentates on it in real-time. Presumably what he’s saying about the assistant and the voice-of-the-balls is correct (someone with more lottery knowledge than me would have to say!) and it’s apparently not the same assistant every week (?) and his timing seems synched with the programme. It does seem slightly questionable that he talks obsessively over the sound of the live feed all the time (perhaps he knows that no-one can be watching BBC and Channel 4 at exactly the same time – though someone might have thought to do this or record them both!) as if in order to drown out the details.

Another unaccounted-for factor is
(4) how he has to explain up-front that the lottery may not get to the key moment in time, and they may have to end the programme. Presumably they would have to quickcly splice in another ending if that happened.

Yeah I don’t believe that he’s reading the numbers out while he’s writing them down – this is just scribble and the voice-over is done from the new live segment (like when he’s in the gorilla suit, if you remember this one)… then he’s handed the completed card just before the splice.

42. What if it is just the last 2 seconds of the ball holder being turned?

I did’nt think u could see Derrens face as it was zoomed in so you could see the ball holder being turned.

In that case…
14 million combos
28 million seconds
466666 minutes
7777 hours
324 days
that leaves 40 days of ball/shot setup for each combination

I’m not convinced it’s how it was done, but i feel it’s important that you dont see its actually Derren as he turns it round in the last few seconds of the reveal.

43. mmm, had only seen the footage once before i posted that, seems u do see fairly clearly that its derren as he turns it, intrestingly the turn itself seems to be around the 2 second long mark…

i dunno now lol

44. I agree with stephen jones from above….

45. 1. Film about 275,000 combinations by filming 50 times an hour for 14 hours for about a year to achieve (this will get at least 5 numbers, also elinate unpopular numbers statistically)
2. Add a cross on the floor next to the tv to stand in the correct position and keep still.
3. Cover face using hand and keep still to improve computer editing.
4. do not have any windows or people or moving objects in the area.
5. Film in a place with no natural light. (to help with lighting)
6. Put all the footage on a computer to edit later.
7. Walk through the studio for no reason, so that a handheld camera can be helped to edit. (A fixed camera will look jolty and they could have used a fixed camera so why didn’t they?)
8. Play film using a computer, with a window of the BBC lottery draw in front of the tv area.
9. Splice the film at the point where the balls stop rolling to choose the correct films using a computer program to choose the ones with the numbers. You will notice the light on the walls change ever so slightly at that point.
10. from the 275,000 clips the correct one is chosen after the last ball stops and is finally spliced in.
11. Remember this is a man who flipped a coin to land on heads umpteen times in a row and it took about 16 hours filming per day for x number of months!!!! Do not underestimate this man’s determination!

46. Not sure this has been mentioned but he said they may cut out if they miss their window of opportunity. I reckon he did enough pre-recordings to give himself a reasonable chance of doing it – if his combination did not exist in the pre-recordings, they would have cut out and he would have done it another time.

47. I think this is correct…

Splice point is @ 4.44ish on the youtube clip linked above… Just as the commentator says “and the sixth one” (there is a slight digital pixalation and derren seems to “slide” backwards a tiny bit. the unstable camera is a deliberate play to hide any slight visual inconsistancies..) With the right technology there does NOT need to be an insider relaying – the transmission is LIVE right until the 6th ball is drawn.. then it is switched for the pre-recorded reveal.. notice how Derren is totally still as they are drawn and ONLY moves again once they are all drawn.

Biggest hint – look at derrens EYES on the final reveal – look how visibly tired he is – he is NOT like that at the start..

In terms of how long it takes to film this.. its horrific – but probably do-able.. assume you want 5 out of 6 balls correct and since he does the balls in assending numerical order it is a nCr calculation not an nPr and then its only 5 correct out of six drawn reduces your number of fims a lot.

Whether he filmed all of these? or some of them or some other combination I am not sure.

48. actually – on reflection I agree with others -t he cut time is 5.14 – you can see it very clearly in the refelctions on the floor – there is a sudden jump there.. also derren walks faster and slightly awkardly from 5.14 onwards…

We Got him

49. I really liked this idea too, it has history with the coin flipping trick he had in a previous show. 55,000 possiblities (5 out of 6 correct) sounds almost possible especially if it is only the bit of flim after he turns off the TV which is pre-recorded.

However, this can’t be right, as already pointed out, in every version he would have to have all 6 numbers correct on the card as these will always have to match what came up in the draw regardless of 5/6 or 6/6 balls being correct, so he still would have to film nearly 14,000,000 version, which just wouldn’t be possible.

50. good point..

Something fishy definantly happens @ 5.14 though.

Could they have filmed some ending sequences where he didnt use his card? eg for each sequence he walks it once with the card and once more without the card so that IF (as is likely) they miss the 6/6 hit they run the tape without derren showing the card and just have him commenting on the numbers

eg he says “so here is my prediction 1 2 3 4 5 and 6 – as you can see I only got 5 of them right which isnt that bad really.. t”hankyou and goodnight…

51. Though it seems crazy this definitely seems like the most ‘Derren’ esque outcome
The allusions to ‘a year of his life’ will be a nice clue if/when he reveals that this is how he did it.
It would also jsut be a monster extension of his coin trick from ‘The System’ (where he implied he manipulated a coin to land Heads ten times in a row, but in reality theyd just filmed it for hours and hours until it happened)
ALSO, Ive just seen a teaser trailer for the explanation show where, at the end, he mysteriously holds up a cardboard snowflake. As all snowflakes are structurally unique, creating a staggering amount of variations, this would allude to the work he had to cover all the bases as, to some extent, lottery results are all unique.
This is the best explanation, no matter how far fetched it seems.

52. Split the screen in 2, that leaves 3 balls on each half.
Each half requires 18,424 combinations.
Thats 36,848 films required.
Assuming 1 minute each, thats 76 eight hour days.
I reckon Id work 76 eight hour days for what he made from this!

53. Nah thats rubbish – just watched the video more closely.
Knowing Derren Brown, he wouldnt have used special effects. Something tellms he he did line up all 13 million combinations of 6 balls, and he then just grabbed the right one. If you had a team of people to line up each combination – thats very possible.

54. Watched it again last night. The 1st ball (before he turns it round) raises up, after the 6th ball is drawn. So I assume this is where the cut is. Only that part of the screen, where the stand is changed. Derren is live all the way through after the long shot from the back of the studio. I agree with someone who said thats where the camera man (seen as Derren enters) is changed to a computer controlled gimble which would give the illusion of a real person, but would in fact be able to exactly match the pre-recorded footage “shakes” and the live “shakes” and disguise the dissolved cut! So if this is true there would be no need to do all the recorded outcomes as its done live on the night by someone who didn’t line up the balls properly and will be in big trouble(I guess)! If this is true, its a bit of a cheap trick from Derren, who is always brilliant (afirmed after watching “the Gathering” last night, and after seeing ENIGMA Live in June!!). I hope its more cleaver than my guess? I suspect though that he’ll make out he did it one way and really did it another…..

55. I hope its more clever then my spelling too!!!

56. Forgot to also mention that a second cameraman was there so that they could cut to a live tranmission at any time in case anything went wrong (i.e numbers didn’t come out. Then Derren can apologise and say that it didn’t go as expected.

57. SERIOUSLY??

it is totally possible that they could splice into the live feed. thats not the issue.

the issue is: could he have recorded all the possible clips? the prerecorded clip would have to start no sooner than when he turns the tv off and last the rest of the show, because the card showing the numbers is in full view for that time. this is a 44sec clip.

so if you’ve read my previous comments you’ll see that it would be impossible to record all of them in a human lifetime.

also, as i’ve said previously, he couldn’t do it with less than 6 numbers because the ‘actual’ numbers are written on the card as he reveals the balls. these ‘5 number’ theories don’t make sense.

CLEARLY this was not his method for a few reasons:

1. ITS NOT F’ING POSSIBLE
2. he’s used it before in ‘the system’ and it’s not his style to repeat something like this
3. this wouldn’t make an interesting program for the friday show
4. he always states that he doesn’t use camera trickery, why would he start now
5. he is way smarter than any of us and would come up with a much better system.
6. he clearly didn’t really predict the numbers, that isn’t the debate, this just isn’t the system
7. ITS NOT F’ING POSSIBLE

58. ps. thank you chris

at least someone listens and understands

59. Actually if you watch the segment at a decent size on a TV, a lot of what has been said here (inc by me) doesn’t stand up to inspection. Sadly. The resolution and jumpiness on YouTube are not representative of what it actually looked like.

For instance, Derren is not in freeze frame during the draw – when I watched it from HDD you could see him moving slightly backwards and forwards in a random way consistent with breathing (particularly clear in rew/ff). I guess it could be slowed down (rather than stopped) film but what is the advantage of that? I think I could see him blinking too / see his eyes moving during the numbers coming out, but someone with HD-tv would have to verify this! Also his lip movements and pen movements when he’s writing the numbers down are consistent with the actual numbers he’s writing rather than being random.

What doesn’t quite make sense with the ‘film all outcomes’ theory is how scattered and hyped, even relieved and exuberant, he appears to be at the end (have a look). Sure, he could be putting this on, but it’d be hard to do it thousands of times over without the aid of a cocktail of Class-A stimulants (such that they’d be injurious to the state of mind I imagine he would need for his career). Those of us whose jobs include boring, repetitive elements (which must be most of us) can vouch for how it’s hard to hype yourself up time and again for something that is straightforward… I can imagine that he could be quite honestly all ‘wish me luck’ in advance even if it was pre-filmed, because you’re relying a lot on the film engineers to splice the right bit in, but his reactions at the end don’t seem consistent with it if it was just one of thousands of takes…

60. more importantly, even if he did all the possible combinations, he’d still have to use an edit to put the correct final version in. If he’s already going to use camera trickery (which admitting to would probably ruin his career) then why not go for the much simpler and less labour intensive split screen theory.
