"Feed me, Seymour!" We've been terrified of Venus Flytraps ever since a giant, extraterrestrial, flesh-eating plant spoke those words to Rick Moranis' character in 1986. The killer, Audrey II (voiced by Levi Stubbs), is simultaneously vicious and lovable, and this darkly comedic sci-fi musical, which was based on an off-Broadway musical that Roger Corman's 1960 comedy The Little Shop of Horrors inspired, is one of Moranis' and Steve Martin's best movies. Anyone hating can end up plant food.
