The Perfect Crime
Title Drop: Frank notes that when a person is expecting to get a letter, it's alright if you don't hear it the first time, because the postman always rings twice. They got off murdering Nick scot-free, but Cora is now dead and Frank on his way to receive the death penalty. He says that the postman has indeed rung a second time for each of them. This is different than the novel. James M. Cain admits that the title was mostly a non-sequitur.
Ugly Guy, Hot Wife
The Vamp: Cora.
Woman in White: Cora dresses entirely in white throughout the film, save for two scenes in which she wears black.
