3 Women (1977)

3 Women is a 1977 film directed by Robert Altman, starring Shelley Duvall, Sissy Spacek, and Janice Rule. The story came directly from a dream Altman had, which he did not fully understand, but nonetheless adapted into a treatment, intending to film without a script. 20th Century Fox greenlit the project on Altman's reputation, but a script was completed before filming, although, as with most Altman films, the script is just a beginning point for what he shoots during production.
The minimal plot involves two women whose personalities are in sharp contrast when they first meet and move in together. The third woman of the titular three is a key supporting character—a mural artist who lives at the same apartment building. The events take place in a small desert community typical of those found east of Los Angeles. For obvious reasons the film has a dream-like quality, focusing more on behavior, mood and mystery than on plot devices.
