Despite the fact that this film has a ridiculous title, it really is quite a little gem. During the 1950's the spread of Communism was the great fear in America and many films reflected this through the analogy of aliens infiltrating society. This movie is one of them....aliens taking over the population without being noticed....the guy next door may be a Communist (or a monster from outer space). Gloria Talbot,who appeared in a score of 50's movies (whatever happened to her?) does a good job as the suspicious wife but she wears one of the strangest pointed bras you've ever seen and even wears it in bed! Tom Tryon sleepwalks through the part of the husband, which in this film is appropriate for the role. He was a very bland actor and eventually went on to a sucessful career as a novelist. The black and white cinematography is well done and the film evokes a sense of impending doom. The special effects, which are limited, are not too bad...remember this was 1958. This film is a standout in a series of lower budget movies of the time but the awkward title may cause some to pass it by. Recommend it to a friend.
