Not for the squeamish, prudish, or sane, The Forbidden Zone opens with a man vomiting into the lap of his dinner companion, ends with the coquettish Frenchy (Marie-Pascale Elfman) hooking up with the sado-masochist midget King (Hervé "Da plane, boss! Da plane!" Villechaize) of the Sixth Dimension and does it all with a song in its twisted heart. This 1980 ultra-low-budget sicko musical lives at the crossroads of John Waters Street and Tim Burton Lane, layering asinine musical numbers over disgusting sex scenes in a partially animated bizarro world populated by dozens of unattractive characters. The Forbidden Zone also launched the career of director Richard Elfman's younger brother, Danny Elfman; the two had formed the Mystic Knights of Oingo-Boingo to score this film. Since that time, the younger Elfman has been behind dozens of movie scores, but is best known for composing Burton's Beetlejuice, The Nightmare Before Christmas, and The Simpsons theme. If the hilarious soundtrack isn't ample motivation for those intimidated by the freakish sex and violence, the side-splitting sight of shrimpy Villechaize coupling with the 225-pound, 6-foot Queen (Tyrrell) is reason enough to slog through the insanity.
