Innerspace is a 1987 science fiction comedy film directed by Joe Dante and produced by Michael Finnell. Steven Spielberg served as executive producer. The film was inspired by the 1966 science fiction film Fantastic Voyage. It stars Dennis Quaid, Martin Short and Meg Ryan, with Robert Picardo and Kevin McCarthy, with music composed by Jerry Goldsmith. Set in San Francisco, California, down-on-his-luck naval aviator Lt. Tuck Pendleton (Quaid) resigns his commission and volunteers for a secret miniaturization experiment. He is placed in a submersible pod, and both are shrunk to microscopic size. They are transferred into a syringe to be injected into a rabbit, but the lab is attacked by a rival organization led by scientist Dr. Margaret Canker (Fiona Lewis) planning to seize the experiment and steal their technology.
