This is one of the many early sci-fi movies released in the 1950s. Standard for these types of B-Pictures was to put more drama and excitement in the film, than real science. Few directors during that day and age ever sought good solid factual science facts, instead they wanted good old fashion monster vs Earthling type action. They were hooky and poorly made, but without knowing it, they created the nightmare memories of our youthful dreams. As a result, they gave audiences what they sought, trills and cheap entertainment. The story in this film is the foundation of modern films like 'Alien' and for its day had formulas which worked. Marshall Thompson plays Col. Ed Carruthers and Ray "Crash" Corrigan, the stunt man for many other films, plays the Space Monster called " It ." Dabbs Greer plays Eric Royce. Although it is an early sci-fi movie, when seen through the sleepy eyes of a youngster, at the Drive-In theaters of the day, it's nothing less than a Classic. Fun for anyone with a yearning to be frightened by a space monster. ****
