The plot, very briefly, involves men from Mars who want to stop Earth from exploring their planet. The Martians travel through the galaxy to inhabit the bodies of a scientist and his family - that is, there is the "real" scientist and his family, and then there are their "body doubles" (the Martians, carrying out their mission). On top of this grave threat to humankind, there is a subplot as we view a crumbling marriage between the two leads. But I wondered if anyone who saw it really cared about them since it was definitely a B-picture. (Kent Taylor and Marie Windsor star as the scientist and his wife).
There were some truly creepy moments in the movie, though. Claire Fielding (Marie Windsor) learns from her son that there is an open door on the estate property where the family is residing. She goes to lock it, then hears movement around her. She becomes scared and hurries on. Suddenly her husband is standing there, with a look that is malevolent. "Where are you going, Claire!" he asks in an a threatening voice. We the audience know that it's really a Martian, but we watch from the point of view of Claire, who's never seen her "husband" this way, and the effect is unsettling. Another weird scene involves the daughter and her doppelganger - the doppelganger looks at her with evil intent. Not to mention what the daughter's doppelganger does to the young love interest of the daughter. As for the rest, watch and find out.
This film is better than its low rating, and I'd say if you like those low budget scifi's from the 50's and 60's this one is definitely worth your time.
