Jack O'Halloran(I)

It was his idea for his character in the Superman movies to be mute.

I wasn't pleased at all. Lester was never rude to me, but I didn't like his attitude toward filmmaking. Lester had his way of making movies, God bless him, but to me, he was nowhere near as professional as Donner. Donner was a pro who knew his job and did his homework. Superman II is a great movie, but it would have been better if they went with the Donner version.
