Superman is a more difficult casting than Batman. I would say the measure of how great Cavill is as Superman forces a completely different character. How you can make a movie in the same series where Russell Crowe is Superman's father...that just seems dumb doesn't it???
I guess everything is burnt out and all will be moving to "alternate universe" stuff.
I don't think Hugh Jackman was too worried about being typecast...he squeezed every $$ out of that role. You act your way out of being typecast, some can't.
