Batman & Robin
The Protagonists:
Dick Grayson, the Batman- Adrian Grenier
The man who Batman would call partner, Dick Grayson now has the unbelievable job of filling the Batman's (very large) shoes. Nervous to say the least, Dick still has all of the skills necessary to take on the mantle. If any of you watch Entourage then you'll know that Adrien Grenier's character of Vinny Chase is an up and comer learning what it's like to reach the big time. I also think that he's way optimistic enough to play off of the near psychopathic Damian.
Damian Wayne, Robin the Boy Wonder- Michael James Olsen
Damian is a hard character to do because he's a maniac locked inside of the body of a twelve year old. I see him being a very good contrast to Dick, disobeying his leader at every turn and belittling him to no end. Since Damian needs an inner rage and jealousy at Dick for being accepted as Batman's successor. Olsen played a similar character as the young Victor Creed in Wolverine, showing signs of jealousy over his own brother that would be necessary for Damian.
Alfred Pennyworth- Michael Gambon
Feeling the loss of essentially his son, Alfred Pennyworth would work extremely hard to see to it that his grandson Dick doesn't befall the same fate as Bruce. Taking an almost obsessive role in how Dick should act, Alfred would come to learn that Dick can handle being the Batman only with Alfred's help. Michael Gambon did this greatly in the fifth of the Harry Potter films as he tried to shut of Harry to keep him from harm. It's very similar character turns that could be translated well towards an Alfred without a Bruce Wayne.
Commissioner Jim Gordon- Tom Selleck
The tough cop, the old veteran, and the caring father are the aspects that sum up the character of Jim Gordon. This is a Gordon who knows something has changed significantly in Gotham and is going to get down to the bottom of it. I'd want this Gordon to be a more man of action than has been portrayed just because it seems like he would like to take things into his hands more now that the Batman has been replaced. Tom Selleck might seem like too much of a man's man for the role of Gordon but that's exactly what he's supposed to be, a man's man.
Barbara Gordon, Oracle- Lake Bell
Playing the role of intelligencer, technician and girlfriend of the Batman is hard enough without having to do it handicapped. Barbara Gordon is obviously a woman who knows that the job will always come before love and wants to do everything in her power to keep Dick safe. Each of these characters reacts differently to the rise of the new Batman, but Barbara is the only one who sees him knowing she'll never have enough. Lake Bell might not be familiar to most and has done mostly comedy roles before but she's always played tough characters before and I think she can play a tortured Barbara Gordon really well and has a very down to earth look to her.
