Yeah that wasn't actually Cage but a mock up of him so they could see what the suit would look like. I guess he wasn't available that day for costume tests. This movie would have just made "Batman Forever" and "Batman and Robin" look like Oscar contenders in comparison. People shouldn't complain about "Superman Returns" after watching that footage. At least Singer understood a little bit better than Burton did who and what Superman was. This movie would have been a travesty.
