Did You Know?


The plot of this movie was partly borrowed from for the first season episode I Dream of Jeannie: The Moving Finger (1965). In that episode, Captain Nelson works as technical consultant for a studio making a movie, in which an American astronaut, shrunken to the size of a pinhead, is injected into the bloodstream of a Soviet astronaut, works his way to the brain and retrieves information vital to the defense of the country. The screenplay to "Fantastic Voyage" was completed in 1964, from an original story that was written in 1963. See more »

Pretty good little film.
23 July 2002 | by (Chantilly, VA) – See all my reviews

To answer everyone's question about how did Issac Asimov resolve the Proteus issue at the end of the movie; in his novelization of the film (which is a very good sci-fi book on its own), the sub comes out with everyone else in the teardrop along with "a very surprised white blood cell." The scene with Donald Pleasance gave me chills when I saw it as a child and having recently seen it again, it still is creepy. I think this is due to Pleasance's performance more than anything else. I do have to say that seeing Stephen Boyd being driven around the LA Sports Center (subbing for the top secret research center; they had to have everything removed by 5:30 in the afternoon the week they filmed there because sporting events were going on at night) in a golf cart seemed a bit silly but I guess that showed how important he was. With these kinds of films, one has to ignore all certain types of questions about how come this did or didn't happen when the scientists did this and just relax and enjoy it.
