Explanation of how this could work: Angier has the key on him when he's duplicated. The original thinks of it when he's in the box and gets out, then the blind stagehands move out the only slightly less heavy box. The prestige doesn't bother checking, either because it makes him feel guilty or he's so desensitized after twenty or so nights that he gets bored and doesn't bother checking, and intentionally (at least from his subconscious) brushes off thinking too much about the key.
- The tank was locked from the outside.
- It's still possible that one night Angier forgot to lock it. It only had to happen once out of a hundred-show run.
- It's a trick tank; they show you the panel. The only difference is that a pick-guarded padlock is used instead of the show padlock.
- Alternatively and relating to the below as well, Perhaps after killing the first clone, Angier realized that because of the risks, he should have a double, so he kept one, and just one, alive. And when Borden/Fallon killed Angier, that last Angier just... let it go, because he was done.
- Though if he was willing to trust a double, one wonders why they didn't simply perform the trick as Borden did using duplicates instead of twins.
- Because, as Angier explains in his "World of Cardboard" Speech, the whole reason he performs is to see the audience's moment of wonder at prestige. The reason he could never work with a double (and the reason he ended up cloning at all) is because he wouldn't be able to see it. Both clones would have this motivation, so neither would be willing to do what the Bordens do and take it in turns.
- But there is a clone that didn't die, the one that was created when Angier first demonstrated the machine in order to get the booking. After all, at the time he still didn't have the drop tank, meaning that at the end of the story there is still one Angier and one Borden...
- Angier shot that one. It was why they made such a thing of him putting a pistol next to the machine.
- Angier shot the clone he created when he first tested out the trick, but there's no indication that he killed the clone he made when he demonstrated the trick to get the booking for his final run of shows. He could easily had killed him one way or another, though.
- If I recall correctly, when Angier first demonstrated the trick, he had blind stagehands, and the Angier in the machine (nonprestige one)dropped under the stage (or at least disappeared). Odds are, he did have the drowning set up already.
- Tesla also never denied making a machine for Borden, he could have made a machine and Borden could have found out how it worked without Tesla knowing, explaining why Tesla and his assistant didn't know exactly how the machine functioned.
- It took me looking this page's history to make sure that I hadn't made this entry. I'm convinced this is true. It also adds new subtext to Borden's line:
He came in to demand an answer and I told him the truth. That I have fought with myself over that night, one half of me swearing blind that I tied a simple slipknot, the other half convinced that I tied the Langford double. I can never know for sure. be the
- Wow, this may be the best WMG entry ever.
- In one of Sarah's last scenes with Borden, she yells, "I know what you are!"
- One of Sarah's lines mentioned that she "knows" when Borden means it when he says he loves her. One twin really does love her and the other loves Olivia. Even one of the scenes with Olivia and Borden shows Borden indifferent when Olivia wants affection. He'd much rather be with his wife but he's on the wrong "shift".
