I just watched the 1924 Soviet film
Aelita Queen of Mars, which was based on a Tolstoy story and may have been the first interplanetary science fiction movie ever. It was pretty cool, even if watching a silent film is a chore by today's standards. The ending features a propogandist Bolshevik revolution on Mars, but as is often the case with movies from that era it kind of satarizes the revolution under the noses of the Soviet censors at the same time. Really amazing sets and costumes which clearly had a huge influence on visions of the future to follow on both sides of the Iron Curtain. This movie predated Fritz Lang's Metropolis by three years, so it may even have influenced him. The cityscapes are certainly similar.
