Mystery Men is one of cinema's best parodies of superheroes, debuting twenty-five years before it would have been a far more relevant riff on the genre. Released in 1999 to mixed reviews and lackluster box office results, the comedy has developed a cult following in the subsequent years. Following a band of self-proclaimed superheroes, the Ben Stiller-led Mystery Men pokes consistent fun at the genre. While the primary frame of reference for the film is movies like the Tim Burton Batman films, the themes and gags from Mystery Men work better in a post-Marvel Cinematic Universe landscape.
