You may think you know Robert Hegyes and Lawrence Hilton-Jacobs from their roles, respectively, as Juan Epstein and Freddie "Boom-Boom" Washington on the classic ABC sitcom Welcome, Back Kotter. But that's only because you haven't seen them play Vietnam War vets who get a day pass from a mental hospital and end up as targets for psychotic war games in Kill Crazy (1990). And aside from those Sweat Hogs, Chuck Saale even plays a character simply named Cotter! Writer-director and muy macho muscle-man David Heavener stars as Alexander Grady Puckett, one of the dispatched patients who, when attacked, erupts into a one-man army of combat chaos. Danielle Brisebois has a topless scene that will drive you crazy from the heat.
