Legendary B-movie character actor who appeared in many of the great and not-so-great cult horror, action and sci fi movies over a 60 year career, including Gremlins, The Terminator, and Piranha. If there was a B-movie Hall of Fame, he'd be in it. As part of a running gag, he played variations on the same character "Walt" in many of his movies, including the scene from "Night of the Creeps" below.
