Most crewmembers involved with the film never did anything else in filmmaking after the release of "Gordy."
This film was originally conceived in the 1970s by Green Acres (1965) creator Jay Sommers and writer Dick Chevillat as a spin-off starring recurring character Arnold Ziffel the pig.
The movie poster features a skyline of the city of St. Louis, though none of the film was actually filmed there.
Tom Lester (Eb Dawson on Green Acres (1965)) appears as a Truck Driver. Jay Sommers, who created the sitcom with producer Paul Henning and developed with Dick Chevillat, offered Lester the role.
