Halloween (1978)
The role of "The Shape"—as the masked Michael Myers character was played by Nick Castle, who befriended Carpenter while they attended the University of Southern California. Nick Castle admitted that the only reason he accepted the opportunity was for a chance to witness what goes into directing a film. "My only reason for being on the set was to kind of demystify the directing experience for me, because [director] John [Carpenter] was a pal, they were shooting the majority of this near my house and John said, 'Well, why don't you just be the guy walking around in the mask and you'll be here the whole time?'"
Castle became a director, taking the helm of films such as The Last Starfighter (1984), The Boy Who Could Fly (1986), Dennis the Menace (1993), and Major Payne(1995).
