Edit = A lot of people think this movie was based on an Isaac Asimov novel. The truth is that Asimov did a novelization of a script written by Harry Kleiner, based on a story by Otto Klement and Jerome Bixby.
The novel let Asimov flex his muscles and come up with all kinds of ways the miniaturization process could have worked.

That’s a trip down memory vein! I saw this at the drive-in, and rode the Inner Space ride at Disneyland.
Loved that movie as a kid.
