Radioactive Man was a feature film adaptation of the comic book and television series of the same name. Rainier Wolfcastle was chosen as the star of the film, although a producer suggested Dirk Richter, star of the teleivision series, despite the fact that he was dead. The producers needed to film it in a location that had a Nuclear Power Plant and a gorge. They chose Springfield, assuming it had to be a good place because they ad found in Variety was small and incorrectly spelled (as "Flim Springfield").
