There is water all through the movie. Altman says the opening shot represents the amniotic fluid surrounding a fetus. The second shot shows old people descending slowly into the exercise pool-returning to the water from where their lives began. A wavy line that drifts across the screen from time to time might be an umbilical cord. Willie's sinister images live at the bottom of the swimming pool, and at a crucial turning point Pinky jumps into the pool from the balcony, is knocked out, rescued, and taken to the hospital.
Altman says Ingmar Bergman's Persona was one of his influences, and we can see that in the way Pinky does secret things to hurt Millie, spies on her secrets, and eventually tries to absorb and steal her identity. Persona has a central moment of violence in which the film seems to break and the story must begin again, and Pinky's dive into the pool works in the same way, as a definitive tear in the structure of the film. It reassembles itself with Pinky in control. She wears Millie's clothes, uses her social security number, reads her diary. In an early scene, Millie assigned them each a twin bed, and now Pinky moves over and takes Millie's bed. Millie calls her "Pinky" and she explodes: "How many times do I have to tell you? My name's not Pinky! It's Mildred!"
Shelley Duvall's reaction shots during these developments are a study in unease. Millie knows something sinister is happening, but is confused and baffled by Pinky's behavior. Consider the strange scene in the hospital, when two visitors (John Cromwell and Ruth Nelson) appear and identify themselves as Pinky's parents. Pinky says she doesn't know them and has never seen them before. Certainly they look too old to be her parents (Cromwell was in his nineties when the film was made). Who, then, are they? Imposters? Grandparents or adoptive parents? We never really know. Pinky arrives in the desert without a past and essentially without an identity, and simply takes Millie's. And all the while, at a deeper, instinctive level, the Willie character exists beneath their consciousness and will eventually absorb them both.
I saw the film first at Cannes, where it won the best actress award for Duvall (she also later won the Los Angeles Film Critics award, and Spacek won with the New York Film Critics Circle award). Altman told me the story came to him in a dream: "All complete. The story, the casting, everything." He wrote it down and tried to film it as he dreamed it. Like many dreams, it ends without concluding, and seems to shift toward deeper and more disturbing implications just before fading out. In his DVD commentary, Altman speculates about the film's meaning just as a viewer might, acknowledges that some aspects remain a mystery to him, and provides a startling possibility about the film's last shot. The camera pulls away from the house where the three women now live, and pans over to a pile of discarded tires. "If you were to ask me where I think Edgar is at the end of the film," Altman says, "I think he's buried under those tires."
But of course nothing concrete in the film supports that. No matter. The movie is whole and complete without being lucid and logical. It circles back on itself, Altman says. There are scenes of acute social observation, including the degrees of cruelty that Millie must endure, and details of specific behavior, as when Pinky squirts a cheese spread on crackers, and then spills a bottled shrimp cocktail on her dress. The senior center is run by a couple who seem to have traded genders; the doctor seems effeminate, and his female administrator seems masculine. Much is made of specifics: how to use the time clock, how to get off early on Fridays, how "we don't like the twins." Sometimes the details repeat as in a dream-the way Millie's yellow dresses always get caught in her car door, for example. Gerald Busby's ominous atonal score is a counterpoint to such daily events.
And against these realistic details Altman marshals the force of dreams. In dreams we test new identities, cast our friends in shifting roles, and find ourselves inexplicably at new jobs or in new places where the rules are explained but we never quite understand them. Here the dream is perhaps shared by all three women, each one imagining the other two, each one lacking what the others possess. As men rumble without consequence in the background, they feel their way through mystery toward each other, Willie with sad resignation, Pinky with avid emotional hunger, and Millie, poor Millie, because she knows not what else to do.
