10 Actors Who Refused To Change Their Bodies For Movie Roles
8. Gene Hackman Won't Go Bald For Anyone - Superman

Not for the last time on this collection of stars who refused to physically alter themselves for the sake of a part, here's an actor who simply would not budge on their follicle stance.
But whereas the other names on this list were completely against picking up a can of hair dye or simply changing up their preferred style a touch, the legendary Gene Hackman had to deal with the reality of kissing goodbye to his beloved locks completely in order to play the arch-nemesis of the Man of Steel himself.
And just how did he deal with this staple of the supervillain's well-known look? Well, he told Warner Bros. where to go, of course. A decision likely influenced by Richard Donner already mischievously tricking The French Connection star into getting rid of his moustache for the 1978 flick.
Instead, Hackman sported a bald cap for the eventual moment Luthor is finally revealed in all his slap-head glory in the closing stages of the flick. But even that moment came after the star had outright refused to be seen in a skin-coloured swimming cap, only to ultimately relent for that aforementioned moment he was sent to jail by Supes.
