Following up on yesterday's failed John Carter of Mars demo reel, here's some test footage from another, far weirder movie that also almost happened. This one: Tim Burton's Superman Lives, the late-'90s superhero movie that was going to stuff Nicolas Cage and his flowing, raven hair into the Superman suit. A documentary on the subject--appropriately titled The Death of "Superman Lives"; What Happened?--will be available here on Thursday, but The L.A. Times has a fascinating early look with some footage of Cage testing his movement in the shiny, scoop-neck costume he would have worn. It's pretty weird. Maybe not as weird as Nicolas Cage in a bear costume punching a woman, but you know, pretty weird.
