Trivia: In this film the title character is never referred to as "The Toxic Avenger"; he is only referred to as "Monster Hero." In his first book, "All I Needed To Know About Filmmaking I Learned From The Toxic Avenger," the director Lloyd Kaufman revealed that the reason for this was because the working title of the movie was "The Monster Hero," and that the change to the title "The Toxic Avenger" only occurred at the "last minute." The character was consistently referred to as Toxic Avenger, or Toxie, throughout this movie's three sequels: "The Toxic Avenger II," "The Toxic Avenger III: The Last Temptation of Toxie," and "The Toxic Avenger IV: Citizen Toxie."
Trivia: A young Vincent D'Onofrio was cast to play the part of Bozo in the first Toxic Avenger film; however, before filming began, D'Onofrio brashly asked for a pay raise and was immediately fired. D'Onofrio was replaced by actor Gary Schneider.
