The Andromeda Nebula

The Andromeda Nebula is a 1967 Soviet science fiction film starring Sergei Stolyarov and directed by Yevgeni Sherstobitov at the Dovzhenko Film Studios. The film was originally intended to be the first episode of a series of films, alternatively titled as The Andromeda Nebula: Episode I. Prisoners of the Iron Star. However, the remaining parts were never made. Officially, it was due to Stolyarov's death, but also because the trilogy's entire budget was spent on the first film and also because the society on the alien planet was seen as criticism of the Soviet Union.
