It 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. It earned $25.9 million in worldwide theatrical rentals and won an Oscar for Best Visual Effects, the only film directed by Dante to do so.

Joseph James Dante Jr. is an American filmmaker, producer, editor and actor. His films—notably Gremlins (1984) alongside its sequel, Gremlins 2: The New Batch (1990)—often mix the 1950s-style B movie genre with 1960s radicalism and cartoon comedy.
