Castle agreed to put the Michael mask back on for this year's reboot, but only for one scene: when Michael and Laurie Strode come face to face for the first time in 40 years. It's a poignant moment, given that this reboot ignores all the other movies and is a direct sequel to the very first film.
Apart from the 1978 and 2018 versions of Halloween, Castle has only appeared in bit parts in three other films. The majority of his credits are actually off camera; Castle wrote the '80s Kurt Russell classic Escape From New York and directed such iconic '90s films as Dennis the Menace, Major Payne, and Mr. Wrong. (Yes, Michael Myers directed a rom-com with Ellen DeGeneres and Bill Pullman.)
