SFT-S01E06-No Food for Thought

Science Fiction Theatre is an American science-fiction anthology series syndicated and broadcast from 1955 to 1957. It was produced by Ivan Tors and Maurice Ziv. A total of 78 episodes was produced.
Broadcasting a total of 78 25–26 minute episodes, the series was also known as Beyond The Limits for repeat syndication during the 1960s, and alternatively as Science Fiction Theater.

Opposite to what happened during the 1950s, the first season was filmed in color, but to cut production costs, the second season was filmed in black-and-white. The producers had originally thought that color television broadcasting would progress faster than it actually did.
Episode 6 of the first season: No food for thought
