Re: It's a Bird, It's a Plane, It's the Superman Costume Thread! - Part 1
Without having seen the costume in action, I think its gone down well enough with those who've seen the set pictures to not have to revert back to the trunks. And the better the film is, the more forgiving people will be about costume or story changes.
That said, it seems like every super hero costume gets updated or tweaked in some way come the sequel, so I'm sure if we get MOS2, I think we could see more changes.
