The synopsis from the IMDB.
In need of cash, Roger Cavendish and his valet take a job escorting the perfect woman for a night on the town. She is in fact the robotic creation of Professor Belman, but it turns out rather to be the Professor's niece Penelope doing a pretty good imitation of the perfect Olga who winds up with them in the bridal suite at the Hotel Splendide.
Miles Malleson will be familiar to American audiences, perhaps, as the Grand Vizier in Conrad Veidt's Thief of Bagdad (he is stabbed to death by the Silver Maid). He's also the vicar in Peter Cushing's version of The Hound of the Baskervilles.
Bill Warren's opinion of the movie: While no classic, The Perfect Woman provided sufficient entertainment and novelty for audiences of its day.
TV series that have exploited the idea of a robot impersonating a human. There was a Twilight Zone episode in which Lee Marvin substitutes for his robot boxer and gets beaten to a pulp (one of my least favorite Twilight Zones).
My Living Doll (starred Julie Newmar) Sitcom
Future Cop (drama, starring John Amos and Ernest Borgnine)
Holmes and YoYo (with John Schuck as YoYo) Sitcom
Mann & Machine (starring Yancy Butler, later of Witchblade) - cop drama
Prototype was a TV movie starring Christopher Plummer and David Morse...a reworking it seems to me of Gene Roddenberry's Questor Project
