Released in 1999, 'Mystery Men' starred Ben Stiller, William H. Macy and Hank Azaria as a trio of wannabe superheroes with unimpressive "powers" who unite with an unlikely group of outcasts to stop an insane villain from destroying their city. Based on 'Flaming Carrot Comics' by Bob Burden and bolstered by a hilarious ensemble cast, the film unfortunately wasn't a huge success at the box office, but -- like its protagonists -- went on to become something of a scrappy underdog in its own right, and is treasured by many as an underrated comedy classic. Fifteen years later, we revisit the cast of this wacky not-so-superhero ensemble flick and see what they're up to now.
