Donald Pleasence
Dr. Loomis
Dr. Loomis is the nemesis of Michael Myers in the Halloween franchise. Loomis was the doctor for Michael, and as a result, he understands him better than anyone else. He appears more than any character besides Michael, being in Halloween 1, 2, 4, 5, and 6. In all appearances, he is portrayed by Donald Pleasence. Malcolm McDowell portrayed him in the Rob Zombie remakes, but this guide focuses on his original appearance. If you want to do his Halloween 4 appearance, you will need facial scar make-up.
