"Radioactive Man" is the second episode of the seventh season of the American animated television series The Simpsons. It originally aired on Fox in the United States on September 24, 1995. In the episode, the film version of the comic book series Radioactive Man is shot in Springfield, with an open casting call put out for a local boy to play the hero's sidekick, Fallout Boy. Much to Bart's disappointment, the part goes to Milhouse. When he tires of the long hours required to shoot the film, Milhouse quits the role, forcing the filmmakers to cease production and return to Hollywood.
