The Perfect Woman(1949)

Overview:

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.
