13. Suspicion (1941)
Stars: Cary Grant, Joan Fontaine, Sir Cedric Hardwicke, Nigel Bruce, Dame May Whitty, Isabel Jeans, Auriol Lee, Reginald Sheffield
When watching Suspicion, it's important to keep one thing in mind: The disappointingly upbeat "Hollywood" ending wasn't Alfred Hitchcock's call. Retaining this information is crucial, since most of the largely sinister film's duration thrives on insidious intentions and the constant threat of murder.
Joan Fontaine, who won an Oscar for her performance, plays a kind woman who ignores warnings about her new hubby, which peg him as a cold-hearted gold digger, and marries him, but then gradually starts to think that he's plotting to off her and run away with her riches. Somehow, Hitchcock convincingly makes audiences believe that the usually debonair and likable Cary Grant (playing Fontaine's untrustworthy beau) could, in fact, be a ruthless murderer.
And, if Hitchcock had been able to fully make Suspicion as he saw fit, Grant's against-type performance would've followed through on that subversion. Luckily, everything that comes before the film's unfittingly happy conclusion is strong enough to make Suspicion richly compelling.
