Most crew never did anything else in filmmaking afterward.
This film was originally conceived in the 1970s by Jay Sommers and Dick Chevillat as a Green Acres (1965) spin-off starring 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.
