What actors would make a good Batman?

It seems like every actor who has played Bruce Wayne/Batman has been more of a pretty-boy than a menacing, grim-looking individual, like Bruce Wayne is supposed to be. Bruce Wayne is supposed to be tall, with short black hair, a rather grim face, a somewhat deep voice, and fairly flat in personality. Bruce Wayne has not been portyayed this way in any Batman films so far. What are some actors who you think may be able to fit this description? I think Karl Urban would fit this description pretty well, visually and personality-wise.
