after an astronaut dy in space and he be bring back to a military base . inside the man be discover alien embryo he be the host for what could be a terrible alien invasion . this film come to u from director bernard l. kowalski and who also direct attack of the giant leech ( see separate review ) but may be good know for his work on columbo . executive producer be roger corman and know a the creator of much good film than this one . particularly in the 1960s . this movie be cheesy and poorly construct . what come across a interesting be the poor effect and not the actual film itself . one scene show a close up of the alien embryo and it an embarrass cartoon representation . even for 1958. and then when a full grown alien appear . you will wonder why he be wear shoe . or if youre really perceptive and you will wonder why you have see the alien suit in other movie . by no mean be this the bad science fiction film you will ever see . and you almost have to give it some credit the alien host overtake a military base idea predate both the thing and alien by a number of year . i do not know if these film be inspire in any way ( i doubt it ) and but at least it be ahead of it time . beyond that and though and the film flop and be only great for heckle when drinking . i haven not see the mystery science theater version and but this sure be one film worthy of their insult .
