Marge Guttman, played by Garn Stephens, is a character in the film Halloween III: Season of the Witch.
Marge Guttman is a store owner who came to town to discuss an issue with the masks she'd ordered from Silver Shamrock, complaining the trademark fell off too easily.
While in her motel room, she began reading a book until she noticed the Silver Shamrock label she'd dropped on the floor. When she picked it up, she noticed circuitry inside. She sat on the bed and began examining the circuitry causing it to shoot a beam of light into her mouth, burning all they way through the back of her head.
After the light stopped, and she lay dead, bugs crawled out from her head cavity.
