In maybe the only time he was a villain on screen Don Ameche uses his dapper charm against type playing a coldblooded man who is trying to drive his very rich wife Claudette Colbert out of her mind. Ameche has been thoroughly seduced by a sultry Hazel Brooks otherwise he'd probably stay a rich kept husband, it's Colbert who has all the bucks in the family.
As part of his plan he has George Coulouris who took a patent out on sinister and who is a photographer in real life going in the guise of a psychiatrist. That and some psychotropic drugs administered and a little amnesia have Colbert thinking she is indeed ready for the rubber room.
Sleep My Love is a combination of Gaslight and Dial M For Murder and the comparisons are obvious since Bob Cummings plays the same kind of role in both films, the sympathetic friend who gives the heroine a shoulder to cry on. He's a bit more proactive in this film than in the Hitchcock classic as he figures out slowly that Colbert is not just imagining things.
Keye Luke has a role of companion 'brother' to Cummings. In fact Colbert and Cummings attend his wedding during the film. What was nice here was that his role was stereotypical in no way. Luke was not constantly make a mess that Charlie Chan would have to straighten out.
As much as the stars give good performances, you will remember Hazel Brooks from this film more than anyone. How a sexy woman like that never had a major career one can only wonder.
Arise My Love was a United Artists release and produced by one of the founding mothers of the studio Mary Pickford. A role she might well have played in the later stages of her career. And Hitchcock himself couldn't have done better with the suspense.
