Fantastic Voyage is a 1966 science fiction film written by Harry Kleiner based on a story by Otto Klement and Jerome Bixby. Isaac Asimov was approached by Bantam Books to write a novel based on the screenplay. It’s often incorrectly assumed, because the book came out 6 months before the film, that Asimov’s book inspired the film, when it was in fact the other way around.
If you’ve seen Fantastic Voyage which is about a crew of biologists who were shrunk down to fit into a microbe-size submarine and projected into the human bloodstream, facing ongoing dangers inside the human body, did you ever dream about being able to experience that journey yourself? Well, you’re not the first. In fact, in the 1920, way before the film, Fritz Kahn, a German scientist, gynecologist and author, developed this idea and had an artist create a poster depicting the metaphor of man as machine in 1926. He called his creation “Man as Industrial Palace.” This was not a joke to Kahn.
