i have the funny chance of see this on mystery science theater 3000 and four year ago . i must admit it wasn not a badly do a some other science fiction or horror movie of the time . the plot revolve around an astronaut that come back to earth with alien embryo inside of him . now the plot be quite weird and well if you can even call that a plot . ( see a space program run out of one building and an old pickup truck be drop dead funny . ) i will admit it be horrible by today standard ( and 20 year ago ) . but i can see myself 43 year ago watch and be charm by this movie . it not even close to the badness of invasion of the neptune men and manos represent hand of fate or future war .
