Seann William Scott, famous for portraying Steve Stifler in the 1999 film "American Pie", was hired as class clown Billy Hitchcock. Scott admired the film and felt that "it's dark and eerie as any "Twilight Zone"". He laughed at his role, saying that "[he is lacking some social skills, he doesn't have quite a few friends, and he's like the tag-along". Scott was surprised when in the script his character was written as fat. The writers eventually changed it for Scott.
