Michael Myers. Tha face behind the mask....

Because of the small budget of the "Halloween"movie in 1978 the cheapest mask that the prop department could find was a Star Trek William Shatner mask. They spray painted it white and messed up the hair. Shatner had no idea of this until years later when he was asked about it in an interview. He takes great honor in the gesture.

On a side note the movie was filmed in 21 days on a budget of $320,000 and made it the highest grossing independent movie at that time.
