Hollywood Zap! (1986)
Hollywood Zap! is a 1986 comedy film written and directed by an obscure Canadian film-maker, David Cohen (no relation to David X. Cohen) and distributed by Troma Entertainment, a company known for its low-budget exploitation films. The film features a large number of unusual character actors, including Chuck Mitchell (Porky's) and Tony Cox (Bad Santa). Scatological humor and extreme ludicrous plot turns punctuate a film that has drawn thematic comparisons to the artistic works of John Waters (filmmaker).
