History in 5×5: Halloween Edition
Due to its shoestring budget, the prop department had to use the cheapest $2 mask that they could find in the costume store: a Star Trek (1966) William Shatner mask. They later spray-painted the face white, teased out the hair, and reshaped the eye holes. Shatner admitted that for years he had no idea his likeness was used for this film. It was only during an interview that someone mentioned his mask was being used. He has since stated that he is honored by this gesture.
