this be an apparently soviet bloc ( from east germany and poland ) film that have be dub into english . how much of the original story be preserve be unknown . several similar film be re dub during the 1960s and the effort be and to put it mildly and very sad . but it easy to tell it communist origin dig those crazy commie hairdo so popular in the 1960s . this film begin with a scientist announce that a famous meteorite that strike siberia and laid waste to so much of it in 1906 be actually a venusian space ship . because of this and he urge the international space effort to change their plan to visit mar and go to venus insteadwho care about the extremely high temperature and metal smashing atmosphere ( two fact never mention in this film ) . in fact and who care that in this film there be no zero gravity in space and rocket decelerate when the engine be cut in space ( space be a vacuum or near vacuumdeceleration do not occur in this state ) and people be throw about the ship a it steer and other fact that be contradict by the law of physic . once the ship near the planet and one of the crew member figure out the venusian language and realize that these people be plan on attack the earth and wipe out everyone . now their goal be to reach those in charge on venus and convince them not to attack . however and various radioactive attack be launch on the team once they near the planet and thing look pretty bad for the earth . and and when they finally be able to penetrate the planet defense and a surprising thing be learn about the venusians themselves . the film look extremely primitive today and but when it debut it special effect and costume be actually quite advanced . with 2001 represent a space odyssey and subsequent sci fi film and we have come to expect a much high level of sophistication in the look of space travel but if you look at the film in context and it be well do . my big problem isn not the effect but the last 25 minute of the filmwhen it just become incredibly talky . again and again and the character just go on and on and on as well a come up with amazingly uncanny conclusion about venusthings they could have only get by read the script . this make the film a bit of a letdown towards the end and but still and i have see bad sci fi film and the dubbing be actually pretty good . worth see for sci fi fan and though most others probably would not be that impressed today .
