In the sleepy town of Santa Rosa CA, Charlotte “Charlie” Newton (Teresa Wright) is over the moon when her favourite uncle, also called Charlie (Joseph Cotten), comes to stay with her family. Everyone loves Uncle Charlie, y’see. He’s charming, fun and generous. And, best of all, he’s not secretly a serial killer.
Oh. Oh, wait.
Yes, it’s another Hitchcock tale of growing mistrust. Our heroine starts to suspect that one of the people closest to her harbours a dark, sinister secret: is her uncle the “Merry Widow murderer”? As the paranoia grows, it’s only a matter of time until it’s Charlie vs. Charlie.
While the plot may sound like a retread of The Lodger or Suspicion, it’s executed better here than in either of them. For two main reasons. Firstly, the idyllic suburban setting is brought to life magnificently by the Great American playwright Thornton Wilder (Our Town) who collaborated on the screenplay. With the setting imagined with such believability, it only adds to the threat when the dark presence of Uncle Charlie begins to creep in.
The second thing that makes Shadow of a Doubt a success is the spectacular performance by Cotten as Uncle Charlie. He’s acts Cary Grant’s performance in Suspicion out of the water. The strong twin-like bond he has Young Charlie at the beginning seems almost genuine, making it all the more ominous when her ideal of him begins to shatter. As Hitchcock villains go, he’s up there with Norman Bates in Psycho and Bruno in Strangers on a Train.
When the two Charlies come head to head it plays out as an allegory of good and evil. The duality of Man: the Good Charlie and the Bad.
There are some baffling plot aspects, such as an absurdly shoehorned romance subplot that comes out of nowhere and goes nowhere, or when the detectives drop their investigation of Uncle Charlies after the other suspect meets an untimely death.
Hitchcock ranks the film as one of his very best. While I personally wouldn’t go as far as that, it’s still an extremely strong thriller that shows off many of trademarks that make up the Master of Suspense.
