i have no idea what the point of this film be . it like a poor 1950 space film do in the late 1960 early 1970 . it start off in one direction and then head off into another . the plot have a spy discover the chinese have a device which may very well destroy the earth by cause an atomic chain reaction inside the earth . meanwhile a space mission to venus be be prepare . suddenly half the crew be replace with woman and the rocket be launch ahead of schedule . once in space the crew watch a the deice destroy the earth and strand in space the crew have to decide what to do next . very dated and even by 1972 standard and and very silly ( the spy get into a top secret center by throw a cat over a wall and i would not talk about the press conference ) i be not sure if i be suppose to be laugh or take this very seriously . clearly it another the commie be out to get u film release about the time that nixon be go to china . unfortunately it doesn not seem to have a point and or at least an end since the picture sort of stop with a conclusion out of left field . simply put it a mess . intriguing enough and in a bad movie sort of way and to keep me watch to the end i arrive there with a great deal of disappointment that that be all . it doesn not add up to much in any real sort of a way . actually the film sort of spiral out of control after the earth be destroy . worth a look for bad movie lover and those want a movie they can laugh at while debate the sanity of the film maker . all others stay away .
