The Prestige w/ Christian Bale, Hugh Jackman, Michael Cane. Directed by Chris Nolan (The Dark Knight, Inception). It looked like a boring premise but it is extremely smart and pulls an amazing trick on the audience that I will never spoil for anyone. EXCELLENT movie.

You may want to watch it 2 or 3 times. Not because its exciting (its not), but the very last second of the movie fucks with your head. When I went to bed after watching it the first time, it stuck in my head. I was thinking "What did he... how did they... hey, didn't they do this...". I had to get up and watch the movie a second time just to watch for clues and WOW they are all there. Highly detailed movie (don't blink even once!).
Can't recommend this movie enough.
