Like any good monster, half of what makes Myers terrifying is psychological. In the film, Michael was dressed as a clown when he committed his first murder and then later uses the almost featureless signature white mask. John Carpenter, the movie’s director, along with his prop team chose a William Shatner Captain Kirk mask and painted it white because it was the most emotionless mask they could find. The mask helped make Myers an unreadable enigma. You don’t know what he’s thinking, what he’s feeling, or why he kills.
