When auditions for this movie were taking place, director Bob Rafelson wrote the name of the actress he thought should be cast as Cora Papadakis and put it inside a sealed envelope. Several months later Rafelson gave the letter to Jessica Lange whose name was inside.
This movie is arguably the first of the 1980s erotic adult thrillers. The picture was soon followed about six months later by Body Heat (1981), like this film, another remake of a film noir, then Fatal Attraction (1987) and Basic Instinct (1992).
This is the fourth version of "The Postman Always Rings Twice" novel. The first was French, Le dernier tournant (1939), the second was Italian, Ossessione (1943), and the third in English and American was The Postman Always Rings Twice (1946). As such, this 1981 film was the second English language version but was the first version in colour as all three earlier versions were in black-and-white.
Apparently, James M. Cain's publishers kept Ossessione (1943), the second version of "The Postman Always Rings Twice", off American screens until 1976 which was only five years before this 1981 movie was made and released.
After the success of this movie, Butterfly (1982), another filmed adaptation of a novel by 'James M Cain' was made and released the following year. Also released in 1981 was Body Heat (1981) which though not technically a remake of Double Indemnity (1944) (also from the novel by James M. Cain) did reference it considerably. The story and characters closely parallel the earlier film. Ned, Matty and Oscar are Walter, Phyllis and Keyes respectively.
When plotting the characterization for the role of Cora, Jessica Lange decided the young woman had first tried to make it as a movie actress in Hollywood, struck out, and eventually married. When Jack Nicholson learned this, he gave her the autobiography of trashy, blonde, B-movie actress Barbara Payton ("I Am Not Ashamed," published in 1963.) Lange based her character's history partly on Payton, who, like her, was born in Cloquet, Minnesota.
The trivia item below may give away important plot points.
The film is notable for its on the kitchen table sex scene between Jessica Lange and Jack Nicholson. The scene was so realistic that many audiences believed that it was real and not simulated sex, a notion denied by the actors. When the scene was shot, the set was cleared. Only director Bob Rafelson and cinematographer Sven Nykvist were present alongside the two actors.
