A Severed Head (1971)

Although he has a mistress (Jennie Linden, WOMEN IN LOVE), a man (Ian Holm) is devastated when his wife (Lee Remick) asks for a divorce so she can marry her psychoanalyst (Richard Attenborough). Based on the novel by Iris Murdoch and directed by Dick Clement (OTLEY). This satire on the British upper class  bourgeoisie and their so called superiority to conventional social mores is quite witty and well acted. Their seemingly laissez faire attitude only a mask for insecurities and conventionality. The film stays faithful to the novel although making Remick's character more glamorous and younger than her counterpart in the book changes some of the dynamics of the narrative. This romantic/sexual roundelay includes Claire Bloom as Attenborough's sister and Clive Revill as Holm's brother as they change partners as readily as they change their clothes. A comedy about adultery and incest was probably quite shocking in 1971 (the book was published ten years earlier) but it presaged the coming sexual revolution of the 1970s. The breezy underscore is by Stanley Myers. With Ann Firbank as Holm's sister, the only other major character in the movie.
