In the late 1990s, Tim Burton nearly made a Superman movie starring Nicolas Cage. It was called Superman Lives, and unfortunately (and ironically), the project was killed before Cage's Superman had a chance to live (and after $30 million was spent). But thanks to the above clip, we can all get a glimpse of how the superhero might have looked.
The clip above, featuring footage of Cage testing out his iridescent blue bodysuit for movement, was culled from the The Death of 'Superman Lives': What Happened?, created by director Jon Schnepp and funded via Kickstarter. The documentary features interviews with many of the failed film's key players—Burton, Kevin Smith (who co-wrote the first draft of the screenplay), and costume designer Colleen Atwood.
