Re: Should they change the costume for the sequel?
Routh has a more Kryptonian suit, Reeve has/had a more Halloween suit!
So, Superman is an alien, who wears an Kryptonian suit and Reeve played Superman with a kind of Halloween suit! Look to those boots from Reeve! Those from Routh are much better!
But i must say: Back then in 1978 they had not the materials to make a suit like they did now!
