The Postman Always Rings Twice (1946)

Though not perfect (the studio and female star could definitely have been improved upon), this is a great noir, and well worth seeking out on blu, as I did, which was on sale and loaded with extras, great ones being feature-length documentaries on the lives and careers of both Lana Turner and John Garfield, each involving huge input from the star's daughter. Essential viewing for fans of the period, and worth both purchasing and rewatches for fans of noir or of either of the stars.
