Jerry Tobin (Darryl Baldwin) doesn't have a single line of dialogue throughout the entire movie. This is in homage to such grindhouse classics as "Halloween" and "Friday the 13th" where the antagonist characters in those films didn't have a single line of dialogue either.
Darryl Baldwin is a trained stuntman, having played the German mechanic for the "Indiana Jones Stunt Show" at Universal Studios theme park for a number of years. He was also a professional wrestler. For "Creepers", he performed his own stunts.
