In "The Prestige", why does Borden keep saying (in the diary as well as to Angier) that he doesn't know which knot he tied at the scene where Julia drowns?

It's got to be one of the twin brothers who tied the knot. One of them would surely know which knot they tied.

If it wasn't for the entry in the diary, you could argue that Angier was asking the wrong twin each time, as it only happens 2 or 3 times in the movie. Perhaps the other twin genuinely did not know, and did not want to ask. But to put that in a diary would be odd. – iandotkelly Sep 30 '12 at 19:37
@iandotkelly But on the other hand the diary was all made up, so you cannot count on this line being a truth just because it was in the diary. – Napoleon Wilson Sep 30 '12 at 20:31
@ChristianRau - yes, but it would be an odd thing for the twins to put in a diary, describing the incident from the perspective of the twin who was there, but then putting the fact that he could not remember the knot from the perspective of the other twin. It would be easier to believe that the responsible twin really could not remember, or it was a deliberate deception to deflect Angier's anger at the truth that he had tied the Langford Double. – iandotkelly Sep 30 '12 at 20:38
@iandotkelly Or the twin who did it didn't even want the other twin to know so he couldn't write it into the diary either (see my 2nd answer). – Napoleon Wilson Sep 30 '12 at 20:48
Why didn't Angier or Cutter simply look at his wifes wrist to see which knot was tied. Seems like a simple solution to see which knot was tied. Why does it matter if Borden/Fallon remembered? Should have been the first thing they all looked for after she drowned? – user29100 Dec 24 '15 at 16:41

First of all, as we learn at the end, the whole diary was made up to lead Angier on a wrong track. This means we cannot rely on the fact that he didn't know which knot it was to be the ultimate truth just because it was in his diary (and even less if he just tells him from his own mouth).

So there are different possibilities and I (as well as the movie, I think) cannot give you a definite answer:

  1. The statement that he didn't know which knot was a lie and he really knew it. He might have written that into the diary to confuse Angier even further or just to not confess his guilt to him, having chosen the wrong knot (or rather the one Julia wanted, as denoted by the nod she gives him).

  2. Like iandotkelly says in his comment, it was indeed always the other twin who told this to Angier and he never got told by his brother about which knot it was because that twin didn't want his brother to know it either (maybe for the same reasons of not confessing his guilt).

  3. He maybe really didn't know which knot it was in the sense that he suppressed the memory in order to not even confess his possible guilt to himself and not having to face his responsiblity for Julia's death.

+1. I had doubts about 2, until I read the diary entry in the script. I've added my thoughts as an answer as it was getting too long for a comment. – iandotkelly Sep 30 '12 at 21:54
About 1 : We can't tell that he tied the one Julia wanted because the Borden who was speaking to Julia in the earlier scene where they argue about the Langford double knot may be different from the one who actually tied the knot (In the sense that the one who tied the knot could be the twin brother and different from the one who spoke to Julia in an earlier scene). I think I agree more with 3. – Mani Oct 1 '12 at 7:31
@Mani I meant the scene when he actually tied the knot right during the trick. There was a small look from Julia into his eyes which could've meant do "do the other knot". Ah wait, I see what you mean, maybe Julia thought he does the other knot, which they agreed to do earlier, but then the twin doing the trick didn't know that Julia wanted (and was prepared for) the other knot. Wow, this tradegy gets a whole new dimension and it could be Borden's secretiveness that lead to her death. – Napoleon Wilson Oct 1 '12 at 7:52
Yes. After reading your comment I thought this would have happened, scene where Julia drowns : I think he tied the "simple knot" (without knowing that his twin brother had a discussion with her on Langford knot) but Julia thought (based on the look that she gave to Bordon/Person tying the knot) he had tied the Langford knot and she tried to use technique which will untie the Langford knot and by the time she realized it was a simple knot it was too late. – Mani Oct 1 '12 at 8:59

As @ChristianRau suggests, this could simply be guilt, or suppressed memory. I think it is possibly both, coupled with the fact that Borden/Fallon are twins. From the voice over as Angier reads Borden's diary:

BORDEN (V.O.) How often I've fought with my self over that night .. one half of me swearing blind that I tied a simple slip knot... the other half convinced that I tied the Langford double. I suppose I'll never know for sure.

It seems clear from how this is written that one of the twins believed that a simple slip knot had been used, the other believed that a Langford double had been used. It seems likely that the twin responsible believed he'd tied the usual knot, but perhaps suppressed the real memory as @ChristianRau suggests. The other twin might understandably believe, as Angier did, that he must have tied the more secure double. This is supposition, but seems a more plausible than the other way around.

So when Angier asks Borden directly, during the funeral, or when performing the bullet-catch - it seems likely that whatever twin is asked, he just was not sure - even the twin that was Borden that night might have doubts even if he started out convinced he had tied the slip knot. This would be even more likely if by coincidence Angier asks the twin who was Fallon that night, so would really not know for sure.

It is very complicated writing an answer about identical twins pretending to both be the same two different characters. If this is not clear let me know !! – iandotkelly Sep 30 '12 at 21:58
Had to read couple of times, but I got what you are trying to say. – Mani Oct 1 '12 at 7:35
+1 Given that the whole movie uses the doppelgänger motive all the time it is indeed quite plausible to interpret this diary entry in such a literal way. – Napoleon Wilson Oct 1 '12 at 7:53

It's possible that one of the twins deliberately tied the Langford double knot, knowing Julia won't be able to break free from it in time, in order to sabotage Angier's act and eliminate the business competition - so that the only great magicians remaining in town would be the Borden brothers.

This ruthlessness in business, this willingness to sacrifice both human and animal life for the sake of fame and profit, is paralleled both in the story of Edison's men destroying the fruits of Tesla's hard work, and thus eliminating the competition, and in Angier's own story of destroying himself by drowning, over and over in agony, for the sake of putting on a sensational show. If these men were willing to sacrifice the lives of beautiful birds, their fingers, the happiness of their romantic partners, their own happiness, and even their own lives to sabotage each other's acts and prove the more successful in this business of creating illusions, why wouldn't at least one of the Bordens have it in him to sacrifice the life of an innocent and beautiful woman and the happiness of his business rival in order to nip his competition's success in the bud and come out on top.

Maybe this Borden was a plant from the start, wishing to work with Angier in order to ruin him, just as Olivia was a plant sent to work with Borden in order to ruin him. Maybe he tied the wrong intentionally, after having tested it on his own and determined that it is not possible for anyone to wiggle out of it in time, and maybe he convinced Julia beforehand to be daring and not to protest when he ties it. We can't discount this possibility. This whole movie is about the ruthlessness of business, about how vicious people can become towards one another and how cruel even towards their own selves when they value business success, fame and profit more than life itself.

Interesting theory, yet I don't think that fits to Borden's character, whose sabotage on Angier always was a reaction to Angier's tries for sabotage and never crossed the line of seriously harming other people. It was always Angier that took this competition to the level of kidnapping and finally murder. Borden always worked quite hard for his art. In the same way I don't think Borden considered Angier as a serious competition (at least not at that time), given the amazing trick he had up his sleeve. – Napoleon Wilson Aug 7 '13 at 8:17
And you might want to extend that answer in order to better answer the actual question. While the answer might be hidden in this nonetheless interesting post, it IMHO doesn't address the specific problem of the question that well. – Napoleon Wilson Aug 7 '13 at 8:19

I think the Borden twin that answered the question the first time genuinely didn't know. I'm sure he found out later or knew already... we ALL knew... BUT anyways he had to COMMIT to his answer for the remainder of his life. That was the price of living the act.

And I'm sure the fact that it incensed Angier added an element of pleasure for Borden... – London J Apr 27 '14 at 16:30

I think the diary entry was written by both the twins at different times because when Angier gets jealous looking at Borden's perfect family life, he says that he found out later in the diary that Borden loved it and hated it the next moment. Since the twins were living a half of both lives, it makes sense that both of them wrote the diary whenever they were Borden.

The scene in which the wrong knot is tied, leading to Julia's death, comes after Borden's claim that he has a new trick in mind (which involved the twin brother). Maybe that's why the other twin(Olivia's Borden) is the one who tied that knot and he is also the one who is asked that question each time by Angier. We can reason that as following:

  1. the funeral The other twin is guilty and hence he attends the funeral

  2. when Angier tries to kill him at his show performing his gun trick The scene in which Borden tells Sarah about the gun trick is when she tells him he doesn't love her today (which means he is the other twin) This is directly followed by the show scene in which he says that he doesn't know which knot it was.

  3. The diary Right after the twin is shot in his hand, he says that he told the truth. 'One half' of him says that it was the simple knot, other half says 'langford double'. Perhaps one half is the other twin and the other half is Borden. I say so because Bordon is certain that he knows a lot about knots and it was indeed the langford double which could have led to the death.

Guys don't puzzle yourselves. You are requested to watch the movie carefully before you read this comment.

Let's call the first twin "Borden" who loved Olivia (Scarlett Johansson) and was hanged in end, and the other twin "Fallon" who loved Sarah and killed Angier.

It was Borden who tied Julia. He was tieing simple knot then Julia insisted and he tied a Langford Double. Both twins were more curious and smarter than Angier. He did it because he wanted to do something that others couldn't (not to kill Julia as some people suggested)

It was Fallon who wrote the diary, the one at Funeral and same person who got shot at play by Angier. He said that he didn't know which knot he tied because he never asked Borden, because he didn't want to know the truth (or maybe he knew the truth).

Borden's character was less mature in the whole movie. He tied Langford Doubles even though Cutter (Michael Caine) warned him not to, he had an affair with Olivia even though he was married, he went to Angier's play even though his brother told him to leave him to his own damn trick.

The only question worth asking is,"is it possible that Angier encountered the same twin every time he asked which knot he tied". I would say the story goes where the writer points.

This is how the Director explained it.
