TRIVIA

• The plot of the (fictitious) movie made as part of this episode anticipates to a large degree the plot of the Richard Fleischer Movie Fantastic Voyage (1966), which was released more than a year later: 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.
