I'm still pushing for Tom Hanks to take the role of commissioner Gordon. I really get the feeling that he would be good for the part when I'm watching Road to Perdition.
Yes, he played a gangster in the role, but a lot of aspects of that character could be put towards Jim Gordon. In the opening scenes, his family is waiting for him to get home. He's running late, the kids are worried in the mom is trying to save face, telling them that he'll be home any minute. When he gets home, he smiles at the boys and tells him that everything's fine. one of the kids peaks in on him getting undressed for dinner, and they see him taking his hand gun out of the holster like it weighs 1000000 pounds. he comes down for a late dinner, and they try to have some family time when a call comes in. The call is obviously serious nature, and Hanks and the wife are concerned, but still try to put on a brave face. Lots of mumbling about something going down, how many guys etcetera. Wouldn't his ride picks him up, there's definitely a Grimm air, and the guy driving is carrying a machine gun. I could definitely see Gordon going through a similar thing with his family, as he's trying to balance a family life and keep his family from being worried about him when he has to deal with constant crime corruption and crazy is breaking out of Arkham.
Someone mentioned John Goodman as Bullock. I think he'd be good for that role, and I also think he be a good runner up for Gordon. Goodman is a great actor who's really starting to get some interesting rolls now that he's lost some weight, and got his drinking behind him.
