In The Prestige, Angier & Cutter take Fallon prisoner and bury him in a coffin, as hostage for Borden's secret. Borden comes and hands over the key to the diary, then digs out Fallon. Which one of them is it?
I had the same question. I'm not 100% sure, but I remember watching the movie and thinking that the angry twin was Borden when Fallon got put into the coffin but then afterwards at the dinner it seems like the angry twin is extra angry because he just got out of the coffin. I might have missed something but it seemed like a mistake maybe. I think i can tell the twins apart pretty accurately, Bale's performances are great and different for alfie and freddy.
I watched the sequence a few times, and there are multiple signs that the rash twin (who loves Olivia and ends up being executed) is Borden in that scene, and Fallon who ends up in the coffin is the calmer twin (who loves Sarah and survives in the end). Here it goes:
- During their performance that night, Borden kisses Olivia on her hand and looks at her in a way that suggests he is the twin that loves her.
- When Borden and Fallon leave the theater after the performance, Borden says: "I'm walking tonight. Let him come. I don't care." When he walks away, Fallon checks his gun. This scene clearly depicts Borden as boastful and careless while Fallon is shown as being cautious.
- In a later scene in a restaurant Borden is the rash twin (he is called Freddy by Olivia and then gets angry at Sarah). In this scene says: "I had a terrible ordeal today. I thought that something very precious had been lost to me." This sentence makes sense if he was Borden earlier and thought that he had lost Fallon, but wouldn't really make sense the other way.
In my opinion it's pretty conclusive. There is a small hint to the opposite in the restaurant scene when Borden jokingly describes an idea of a new trick: "I am going to bury myself alive every night, and then someone will come along and dig me up." This sounds like he was the one who got buried, but it doesn't actually prove anything because since he is now "Borden" he would be saying this in first person in either case.
