Bale, Oldman, Freeman
These three played their roles just as they should be played.
I remember when Oldman was first said to be Gordon and I'm not sure if I was immediately confident when I heard his casting but when I saw him as Gordon and acting in the movie, it was one of the best casting parts I've ever seen for a Batfilm. Or any superhero film. He's right up there with J.K. Simmons as Jameson in Spider-Man as a sub character.
