Let me first say that this movie isn't half bad. It's definitely better than 'The Illusionist'.
As many people have pointed out, though, the whole 'prestige' thing (it's what the punchline of the magic trick is called) is a bit thin.
On the other hand, I can't wait to work it into my sex life. If I ever get laid again, I'll make sure that 'the prestige' is spectacular. The important part is to yell, "The prestige," at a strategic moment.
Anyway - this movie. Isn't magic tricks a dumb thing to kill / die over? I'm going to kill a guy to steal his juggling movies. Or, like, his unicycle.
