I think Jerry Bruckheimer is the guy for Superman, and probably for Capt. America as well. I don't generally support his movies entirely, but he has an eye for action, and for waving the American flag. Both of these characters call for a treatment like that. Superman CAN'T be huge, because it's hard enough to look ar Clark and not make the connection. I really don't think more Superman movie are needed now that we have Christopher Reeve available on DVD. Those first 2 are "super".
Give me a Bruckheimer Capt. America based on Mark Waid on Ron Garney's run where Cap gets "exiled" and eventually redeems himself by saving the Red Skull's life. Wonderful story, and just the right length for a movie. I'll take Robert Redford as Steve Rogers. That would kick.
