after an astronaut dies in space and he is brought back to a military base. inside the man are discovered alien embryos  he is the host for what could be a terrible alien invasion. this film comes to us from director bernard l. kowalski and who also directed attack of the giant leeches (see separate review) but may be better known for his work on columbo. executive producer was roger corman and known as the creator of much better films than this one. particularly in the 1960s. this movie is cheesy and poorly constructed. what comes across as interesting is the poor effects and not the actual film itself. one scene shows a close up of the alien embryos and it an embarrassing cartoon representation. even for 1958. and then when a full grown alien appears. you will wonder why he is wearing shoes. or if youre really perceptive and you will wonder why you have seen the alien suit in other movies. by no means is this the worst science fiction film you will ever see. and you almost have to give it some credit  the alien host overtaking a military base idea predates both the thing and alien by a number of years. i do not know if these films were inspired in any way (i doubt it) and but at least it was ahead of its time. beyond that and though and the film flops and is only great for heckling when drinking. i haven not seen the mystery science theater version and but this sure is one film worthy of their insults.
