Mustache or not?
There is a whole story about how the studio wanted him clean shaven. But the director and actors conspired to keep the mustache. They filmed X amount of film, when studio head said shave it and re-shoot, they said it would cost 150,000 or some such amount. So they left the mustache.
So, mustache or no mustache? As a beard wearer I'm prejudiced.
Why settle for the lesser of two evils? Vote Cthulhu!
