Jerry Maren had an uncredited role as a Lollipop Guild Munchkin in O Mágico de Oz (1939). Maren later said he regretted making this film because it was in such poor taste, and nothing remotely like what happened while filming his earlier film.
Some posters for the film featured a long blurb that read: "Somewhere, Under The Rainbow, way down low--Chevy Chase, Carrie Fisher and 150 midgets are fighting valiantly to save our country against all Oz!".
When Carrie Fisher was a guest on the The Tonight Show (1962), she admitted that this was one of the worst movies she ever starred in.
The picture was a financial disaster at the box-office and Chevy Chase described the film as "one of the worst movies ever made."
The movie was shot at the same hotel that had been used for the filming of O Mágico de Oz (1939) although was no longer operational.
