Fantastic Voyage is an American science fiction film written by Harry Kleiner released in the UK on 14 October 1966. The film is about a submarine crew who shrink to microscopic size and venture into the body of an injured scientist to repair the damage to his brain. The original story took place in the 19th century and was meant to be a Jules Verne– style adventure with a sense of wonder. Kleiner abandoned all but the concept of miniaturization and added a Cold War element. The film starred Stephen Boyd, Raquel Welch, Edmond O'Brien, and Donald Pleasence. It was 20th Century Fox's final film to use the CinemaScope process.
