Sleep, My Love is a slick, classy thriller from the slickest, classiest director of all time, Douglas Sirk.
Granted, his greatest work was a few years ahead of him, but even when he was making run-of-the-mill potboilers like Sleep, My Love and Lured (1947), Sirk applied not only his considerable skill as a filmmaker to the material, but also his fetishistic attention to details, and his love of the sumptuous and the glamorous.
The film starts with a bang. Alison Courtland (Claudette Colbert) wakes up from a nightmare on a train, screaming. She doesn’t have any memory of how she got there. The last thing she remembers is going to sleep next to her husband in their palatial home on Sutton Place and East 57th Street.
Oh, and there’s a small pistol in her bag that she doesn’t remember having, either.
Sirk introduces all the players in his mystery early in the film — Alison’s husband, Richard Courtland (Don Ameche), her friend Barby (Rita Johnson), Barby’s brother Bruce (Robert Cummings), Detective Sgt. Strake (Raymond Burr), a mysterious man with horn-rimmed glasses named Charles Vernay (George Coulouris), and the leggy, beautiful Daphne (Hazel Brooks) — but it’s not immediately clear how they all relate to one another.
Much of the pleasure in watching Sleep, My Love comes from seeing how Sirk moves all of his chess pieces around the board. It’s clear from the outset that someone is gaslighting Alison, but who is doing it? And why are they doing it?
This isn’t the kind of mystery in which the solution comes as a complete surprise and is explained by a brilliant detective who gathers all the suspects together in a drawing room; rather, it evolves and reveals itself naturally over the course of the film. It won’t take an astute viewer long to figure out what’s going on, but Sirk isn’t trying to pull the wool over anyone’s eyes. He’s simply making a thrilling film that’s beautiful to look at, and succeeding with aplomb.

Deanna Durbin is an absolute delight in this farcical murder mystery. Durbin, a native of Winnipeg, Manitoba, was once one of the biggest stars in Hollywood, but never made a movie after 1948. (She currently lives in a small village in France, grants no interviews, and is reportedly very happy.) In Lady on a Train, she plays a young woman named Nicki Collins. When the film begins, Collins is sitting by herself in a compartment on a train entering New York on an elevated line. She has come from San Francisco to spend the holidays with her wealthy businessman father, and is currently engrossed in a mystery novel called The Case of the Headless Bride. When the train is briefly delayed, she looks out the window of her train car and witnesses a murder. Through a lighted window, she sees a young man beat an older man to death with a crowbar. She never sees the murderer’s face, however, and when she reports the murder to the police, the desk sergeant dismisses her report as the product of the overheated imagination of a girl who loves murder mysteries and can provide no real specifics of where she was when she saw the murder. Also, it’s Christmas Eve, and who want to traipse around looking for a murder that may or may not have occurred somewhere in Manhattan north of Grand Central Station?
Lady on a Train is part mystery, part musical, part noir, part comedy, and part romance. The most surprising thing about this movie is that each element works perfectly, and they all complement one another. (Calling this film a noir is stretching it, but the final chase in a warehouse contains some striking chiaroscuro shot constructions, and is as tense as one could ask for.) Lady on a Train is also a delight for Durbin fetishists, since she has a different outfit and hairstyle in literally every scene. Sometimes the changes are subtle, but occasionally they’re impossible to miss, such as the scene in which she comes in out of the rain and is suddenly wearing gravity-defying, Pippi Longstocking-style braided pigtails.
