Planeta Burg (1962)

aka's: Planet Of Storms/Cosmonauts On Venus/Планета бурь

A group of cosmonauts land on the planet Venus. However, they find themselves in danger from the voracious monsters that inhabit it. The special effects and the background music in this film are both awesome. (In Russian language, with English subtitles.)

Note: This film was later edited and dubbed as Voyage To The Prehistoric Planet and was released in the U.S. in 1965. This feature (and the Russian inserts) were in turn used to create Voyage To The Planet Of Prehistoric Women (1968).
