This was Dorothy Stratten's final film role released while she was still alive. She was killed two months later in a murder-suicide by her husband Paul Snider. According to a September 20, 1980 article in the Pittsburgh Post-Gazette, it was released the day after she died, and quickly pulled from theaters for a later release.
The movie-within-this-movie was the Polish-East German sci-fi film Un viaje a Venus (1960). The film is watched by the characters in the picture and was chosen because the American distribution rights were owned by Crown International Pictures who distributed Galaxina (1980) stateside.
The Batmobile from the television series Batman (1966) is parked in the street in some of the Western town shots.
Involved with director Peter Bogdanovich at the time of the film's US release in June 1980, Dorothy Stratten complained to him that the print ads for Galaxina (1980) also promoted her status as Playboy's Playmate of the Year, upsetting Dorothy who now wanted to be taken seriously as an actress.
