Unearthly Stranger (1963)

A recently married English scientist (John Neville) working on a top secret project and whose predecessor died under mysterious circumstances finds himself under suspicion by the British secret service. The reason is his new wife (Gabriella Licudi) whose behavior is, well ..... unearthly. Directed by John Krish, this minor B&W British science fiction entry is a nice little surprise. Although made in 1963, it has the feel of one of those 1950s sci-fi films, perhaps directed by Roger Corman. While its "my wife isn't human" structure may feel similar to such efforts as INVASION OF THE BODY SNATCHERS or I MARRIED A MONSTER FROM OUTER SPACE, it still manages to have a corker of a twist ending that took me by surprise. Though it's not the kind of movie where the acting matters much, that's still no excuse for the heinous performance by Patrick Newell, who had me cringing every time he came on the screen. If you're a sci-fi buff, especially of the films of this period, then you should definitely check it out. With Jean Marsh and Philip Stone.
