I adore Christian Bale. He's very talented (and has that classic handsome vibe that makes my knees shake xD)
The first time I saw him was a few years ago: American Psycho. That book is one of my favorites and I readed it before see the movie, and I always a hard time to imagine Patrick Bateman.
Then I saw the movie and...damn! Mr. Bale was Patrick Bateman! Now I can read the book and know/imagine everything that happens there with a face, you know? I don't know if I'm explaining myself well, but whatever.
Damn
Also, I adore how he involves with his characters...have you seen The Machinist?
