Galaxina
Galaxina is a low-budget 1980 American comedy/ science fiction film, best remembered for its lead actress, Playboy Playmate of the Year for 1980 Dorothy Stratten, who was murdered shortly after the film's release.
Besides its homages to and parodies of science fiction mainstays Star Trek ( 1966), Star Wars ( 1977), and Alien ( 1979), this film also pokes fun at Western movies. It won the Audience Award at the 1983 Brussels International Festival of Fantasy Film.
A film viewed by characters within the film is a clip from the Eastern bloc film First Spaceship on Venus ( 1960). The clip is used in the film because it was also a Crown International Picture.
