Jim & gang-- they actually used a lot of blue screen in Superman--and, yeah, it was pretty crummy. First of all, no one seemed to have given any thought to the character's costume-- blue, for crying out loud. Duh! So you had composites where pieces of him disappeared. The blue-screen fly-bys in the original version of the film had to practically make him green-gray to keep the image together. This is particularly notieable on the flyby when he's racing past the mountains to save Jimmy Olsen from falling off the dam.

I've watched the subsequent releases of the film on dvd, and they seem to have tweaked things with modern color corrections. The costume is bright blue again. Lotsa wire work on this, too-- from the first Fortress of Solitude shot, through the entire Lois Lane love scene down through the landing-in-prison scene at the end. And I thought the Zopic front projection looked as soft as the old 40s process shots, but everybody seemed to think it was swell.

But for all that, it's all sweet and fun.
