“Heckle” (*1/2 out of four) was a grindingly unpleasant horror show about a vindictive stand-up comic (Steve Guttenberg) who encounters a heckler (Clark Gable III) at several shows who he realizes is stalking him and subsequently trying to ruin his life in payback for all the customers/fans whose lives he ruined. Guttenberg’s strained performance cast against type as a jerk provides plenty of “heckles” but film is otherwise lame and grim. Sadly, Gable III subsequently died shortly after this completed.
