To grab one's attention, there's nothing quite like a screaming face with bulging eyes slowly sinking under quicksand. Few actors could bulge and scream as well as Elisha Cook Jr, and in Dark Waters he's given every opportunity to deserve his fate. Please note that while elements of the plot are discussed, we know the whodunnit within the first 15 minutes of the movie. It's the whydunnit combined with swamp atmosphere and movie-making craftsmanship that make the movie as good as it is.
Leslie Calvin (Merle Oberon) was one of four survivors of a sub attack during World War II. She and her parents were returning to America from Batavia. She wakes up in a Louisiana hospital, distraught, anxious, knowing no one and afraid she's losing her mind. She remembers a sister of her mother, and her doctor encourages her to write. She eventually receives a letter inviting her to stay with her Aunt Emily and Uncle Norbert at a plantation house on Bayou Grandterre, near the small town of Belleville, Louisiana. She sends a telegram saying when she will arrive, but when she gets off the train no one is there to meet her. Her anxiety kicks in, she faints from the heat, and wakes up in the train station being attended to by Doctor George Grover (Franchot Tone). He drives her to the mansion, gloomy and colonnaded, where she meets her aunt and uncle (Fay Bainter and John Qualen) and a Mr. Sydney (Thomas Mitchell). Sydney seems sympathetic and caring; he also seems to run the plantation and to run Aunt Emily and Uncle Norbert. He always wears seedy-looking white suits. He regrets not receiving Leslie's telegram, and Aunt Emily says she doesn't understand what could have happened. Leslie is welcomed warmly and shown her room. Dr. Grover cautions Mr. Sydney on how precarious Leslie's mental health is. As Grover drives off, Mr. Sydney takes Leslie's telegram from his pocket, wads it up and throws it in the trash.
And now in this gloomy mansion on the edge of a swamp, Leslie begins to experience unsettling things...a shutter banging in the night, a lamp she turns off which later comes on, a voice softly calling her into the swamp. Her aunt is sympathetic but dithering. "You're not eating, dear," she tells Leslie. "I do think you should have a hot biscuit." Her uncle is preoccupied. Mr. Sydney is avuncular and watchful. Before long, she also meets Cleeve (Elisha Cook Jr.), the man Mr. Sydney hired to oversee the plantation, a man who urges Leslie to have fun with him, who likes to touch her arm, who blinks a little too fast when he's excited. "It must be awful drowning in quicksand," Cleeve tells her one day. "Water's cleaner at least...faster." "Cleeve," Mr Sydney says, "please...think of Leslie." All she has to depend on is George Grover, a man who is falling in love with her but who may not believe her suspicions. The climax comes in the bayou at night, where the dark water is choked with swamp grass and a solid path can lead to a slow, strangling death in quicksand.
If there's a category called swamp noir, and I see no reason why there shouldn't be, Dark Waters would be a leading example. The film's atmosphere is dark, humid and filled with dread. The mansion not only has seen better days, but so has the old sugar house nearby. It's derelict now and sits right on the edge of the swamp with only a narrow passage leading from shore to the boat dock. Much of the action takes place at night, when many creeping things can hide, a path can be mistaken and a corpse hidden. Merle Oberon and Franchot Tone do fine jobs in the lead roles, but what makes this movie work so well are Mitchell, Bainter, Qualen and Cook. The four never go over the top. While we know bad things are happening, and we know they are part of it, we never find out just how bad things are until the end. Mitchell and Bainter are particularly good. What also makes this movie work is the efficiency and craftsmanship of the screenwriters and the director. They take less than five minutes to establish Leslie's situation, less than 15 minutes to place her in the middle of the plot. From then on, they steadily increase the dread and unease. And then, right in the middle of the movie, they take 10 minutes to put Leslie and George in a Cajun fais do-do, with fiddles, accordions, lots of dancing and the kids of a Cajun family that Leslie met the previous day. It's a great device to ease up on the plot a little and then bring things back with even more tension afterwards.
This is a first-rate and largely forgotten movie. If you like noir and are fond of excellent character acting, this would be a film to add to your collection. The DVD visual and audio are not perfect but much better than you might expect. The DVD is easy to watch. It has no extras.
