I’ve seen this – and the remake! – before, but long enough ago that I only had a few images and plot points in my memory. The twist is so good because the cover story is so believable – boarding school principal Michel is married to Christina, having an affair with Nicole, and is a real piece of shit to everybody, the two of them included, so they team up to murder him. Of course, why wouldn’t they? But the real plot is to get the nervous wife out of the way and collect her inheritance. After the murder plot goes wrong in various nerve-wracking ways, she’s finally scared to death by his apparent resurrection.
The happy trio:
Allegedly, Hitchcock wanted to make this before Clouzot bought the rights, so it’s salting the wound that the private detective is named Alfred. He hangs around the morgue looking for cases to investigate, and latches onto this one without anyone asking him to, then busts the two lovers in the last scene. The staging in this is so lovely. I’d have to rewatch Wages of Fear to see which I like better, but should probably rewatch that anyway just for the pleasure of it.
Alfred is Charles Vanel of Wooden Crosses and To Catch a Thief. The nervous wife was played by the director’s nervous wife Véra Clouzot, who did die of a heart attack a few years later. Costars Simone Signoret and Paul Meurisse would reunite much later in Army of Shadows.
