The "chirping" noise sound effect that represents the speech of the slow moving people at the diamond exhibition is the same effect used for the communicators on Star Trek (1966).
Loosely based on "The New Accelerator" by H. G. Wells.
The set for Morgan Midas's home is the same set used for the Barkley home in The Big Valley.
In the scene when Midas takes Jim and Artie to steal the jewels, all of the other actors are supposed to be "frozen" in time; however, in one close up shot, a man can be seen over Jim's right shoulder losing his balance and moving.
