What if Superman woke up on the wrong side of the bed - every single day?

Actually, that happened in 1983's "Superman III," which is generally regarded as the second-worst of the movies that starred Christopher Reeve (after, of course, 1987's "Superman IV"). But the third entry was really onto something when the squeaky-clean Man of Steel turned into a dirty, drunken anti-hero after being exposed to a synthetic chunk of Kryptonite.

"Hancock," starring box office superstar Will Smith, is onto something too, since it basically takes that idea and runs with it.
