>Gene Hackman initially refused to cut off his mustache to play Lex Luthor in 1978's SUPERMAN. Before Hackman and director Richard Donner met face-to-face, Donner proposed to Hackman that if he would cut his mustache, Donner would cut his too, and Hackman agreed. It turned out later that Donner did not have a mustache at all. He wore a false moustache that he peeled off at the last moment.
Couldn't they cgi the mustache?

Jim Carrey recounts first time meeting Tommy Lee Jones:
"I walked into a restaurant the night before our big scene in The Riddler's lair and [Tommy was there]. I went up to say hi and the blood drained from his face, in such a way that I realized that I had become the face of his pain. He got up, kind of shaking, hugged me and said 'I hate you. I really don't like you.' And I was like 'Wow, ok. Well, what's going on man?' And he said, 'I cannot sanction your buffoonery.' He did not want to work with me."
