In the documentary short, 'Halloween' Unmasked 2000 (1999), it was revealed that the crew had chosen two masks for Michael Myers to decide on. The first was a Don Post Emmett Kelly smiling clown mask that they put frizzy red hair on. This was an homage to how he killed his sister, Judith, in a clown costume. They tested it out and it appeared very demented and creepy. The other mask was a 1975 Captain James T. Kirk mask that was purchased for around a dollar. It had the eyebrows and sideburns ripped off, the face was painted fish belly white, and the hair was spray painted brown, and the eyes were opened up more. They tested out the Kirk mask and the crew decided that it was much more creepy because it was emotionless. This became the Michael Myers mask.
