It certainly has one of the most sensational titles from the 1950s, but I Married a Monster from Outer Space plays down the sensationalism in a story that is remiscent of Invasion of the Body Snatcher. It also has similarities to another great SF film of the era, It Came From Outer Space.
It starts out at a bachelor party. Bill Varrell (Tom Tryon) is returning home when he hits a body in the road. But when he checks, it’s disappeared. Perplexed, Bill is accosted by a monster, who takes him over.
The marriage goes on, and his bride Marge (Gloria Talbott) notices strange things about him – he can see in the dark and he appears to not know things he should. After a year, she begins to realize that her husband isn’t her husband. But by that time the town is infested with these doppegaengers, who keep her from calling for help.
The monsters – aliens – are basically men dressed in rubber suits, but that’s normal for movies before CGI. What makes it interesting is the subtext; it’s quite clear that Marge and her “husband” are having sex, even though she hasn’t gotten pregnant.
The movie portrays 50s paranoia, though the monsters end up being fairly benign.
The cast and director and even the writer were working in televion and probably hoped to make the leap into features. All worked for years afterwards, though stardom eluded them.
The biggest star, and most successful career belongs to leading man Tom Tryon. He grew tired of acting about ten years later and started writing horror novels. The Other was a best seller and a movie, and he had most of his books made into films or TV miniseries.
