Distractingly loose but clever, this 1987 comedy by Joe Dante (Gremlins, Matinee) stars Martin Short as a hypochondriac and Dennis Quaid as a miniaturized test pilot who is accidentally injected into him. Taking a page or two (or a hundred) from the classic science fiction movie Fantastic Voyage, Innerspace details the adventures of traveling through the human body's complicated systems, though in this case, it proves an unusual way for two characters to forge a bond. Dante's endless imagination goes into overdrive here, but the film is more gimmick than anything else and ultimately feels a bit hollow. Fans of Short or Quaid might like it more than most, though Dante's hardcore fans will also appreciate seeing his stock players Dick Miller and Kevin McCarthy. --Tom Keogh
