Apparently, back in the 70s Nolte was approached to play Superman. He didn't want the role, so he sabotaged his chances by insisting that Superman should be schizophrenic.
1) How do you think Nolte could've performed if he wanted to play Superman?
2) What do you think of a version of Superman who had a DSM mental disorder? In this case, it could either be a "mainstream" take on the character or a Elseworlds.
