Look at it, kids. Take it allll in. WE SAID LOOK AT IT.
Yes, that's a long-haired Nicolas Cage dressed as Superman while posing for a police mugshot, apparently. The authenticity of that picture has been disputed, but the fact remains: Nicolas Cage had, at one point, signed up to play Superman ... and he got frighteningly close to actually doing it.
There are several stages to a movie. This is the "super happy rave party costume" stage.
In truth, Cage's involvement is only the tip of a very large iceberg. As we mentioned, Kevin Smith was brought in to write the screenplay, but he had to work with the ridiculous conditions imposed by producer Jon Peters: Superman could not be seen flying, couldn't wear the classic costume (Peters insisted on a black suit) and somehow, someway, had to fight a giant spider at the end. What was the reasoning behind changing Superman's costume, you ask? Peters thought the classic blue-and-red outfit looked "too faggy."
