Just to throw a random name out there, how about Scott Derrickson? His record is short and somewhat mixed, but The Exorcism of Emily Rose was a fantastic film, and The Day the Earth Stood Still showed he could do action well, even if the script and producer enforced casting were less than ideal. His biggest strength is showing how ordinary people react to extraordinary things in their midst, and I think that could be bode well for a Superman reboot, as Superman's existence was more or less accepted as the status quo in the Donner films.
