Having just watched the 3 hr version of Superman: The Movie, I was struck by how good Reeve looked.
Why Don't Any Superhero movies feature comic accurate costumes for their characters?
Superman: The Movie nailed it.
Raimi's Spider-man got very close.
Warren Beatty's Dick Tracy was easy to do, even if Beatty didn't look like Gould's character.
Wesley Snipes' Blade was a 1990's version of that character and pretty accurate, not the Gene Colan Tomb of Dracula guy in the red coat.
The Marvel films have been hit (Iron Man/Black Panther) or miss (most Avengers costumes). These outfits seem more based on the Ultimate Marvel comics.
Gal Godot's Wonder Woman is fairly accurate.
As far as TV goes... the only costume that ever spoke to me was John Wesley Shipp's Flash, and even then, he looked more like Wally West than Barry Allen.
Should costumes return to the Chris Reeve era spandex/cloth? Is there a way to make actors look more iconic in their costumes? Will any actor ever embody a comic accurate superhero the way Reeve did for Superman?
