a lot of the names that are being bandied about by people on forums such as this, are preoccupied by the look and don't really take into consideration the actors ability to act! please think before suggesting actors! my favourite is chris eccleston; yes he has joker features, but that is a bonus; he is a fantastic actor. Bettany is also a fantastic actor, with a few prosthetics he could do it. roth, depp, brody are all fantastic actors. i haven't seen hulme in anything other than matrix where he had little to no opportunity to showcase his talents. glover, isn't convincing; he does look right but this should not be a reason for his casting; although a lot of people seem to be falling into this trap. people if we were to go on looks alone in any film, then ashton kutcher would be awesome!!!
