Black Moon is a 1975 French-West German avant-garde film directed by Louis Malle and starring Cathryn Harrison, Joe Dallesandro, Therese Giehse, and Alexandra Stewart. Shown at the 1975 New York Film Festival, it was distributed in the United States by 20th Century Fox. Despite the film's location in France the film's dialogue is in English.
The surreal mise en scene centers on Lily, a confused teenager (Cathryn Harrison) who witnesses a war between the sexes and finds herself involved in numerous dream-like situations at a country estate. An underlying subtext offers a commentary on the Women's Movement of the 1970s. The film is dedicated to Therese Giehse, who plays the character of The Old Lady, who died shortly after the end of the film.
Malle himself has said about this film: "Opaque, sometimes clumsy, it is the most intimate of my films. I see it as a strange voyage to the limits of the medium, or maybe my own limits." Susan Sontag said it was "mesmerizing", and Kevin Thomas of the Los Angeles Times called it "intensely personal and so very beautiful".
