in case you wonder why roger corman scrap the story line of german sf film he buy and watch one in it original form . this film be on par with tom baker era dr. who show in most respect . process shot and model and special effect be all pretty basic . direction be very slow and the story predictable . like many tv space opera and our explorer land amongst humanlike alien and most of whom be enslave by a mean tyrant . fortunatly and they speak the explorer language and in this case and german . but instead of ming the merciless and it more like clueless . our tyrant boast an army of about 20 guy and no real weapon except handgun and no death ray and no monster and nada . he isn not even that mean . true and he make the couple dozen native of the planet mine some mineral or something with pick and shovel but there be no massacre or real evil deed . his most violent act be to throw a hissy fit and trash his own bedroom . technically and blakes seven be way well . the sound effect and some of the background music a well be just oscillator go wwwwoooooo at different frequency . the rocketship go out of control be cleverly suggest by flash red light and tilt the camera back and forth . the control room be full of big pilot light all flashing in unison and signify nothing . consider the size of the control room set and the rocketship must be about 600 foot tall . it never explain how people get in and out of this skyscraper of a space ship . the entire population of the planet appear to be around 75 people . there be no city and no factory and they never even show the tyrant palace from the outside . there be only a little mine and equip with 19th century style hardware . all the men apparently work in the mine and all the woman dance on the leader lawn all day long for his amusement . what do the people eat . unlike flash and the situation of tyrant or slave or heroic space explorer or etc . be not resolve at the end of the film . you may well ask if there be another reel that somehow do not get show . ok and maybe it unfair to dis a movie like this since the communist film industry must have have a lot of problem . but if a clunker like this come from american international back in 1965 the critic would have pan it brutally . it too dull and boring to be a lost gem and not wacky enough to be a cult classic . if i have to see stuff like this when i go to the movie i might have try to tunnel out of the country too .
