Cary Grant and Joan Fontaine in a still for Suspicion (1941), the first of four collaborations between Grant and Hitchcock.
The film originally ended on a much darker note, with Fontaine’s character knowingly drinking poison prepared by her husband—but sending a note to the police that will condemn him after her death.
Grant preferred this version to the more ambiguous finale that the studio demanded. As he explained, “I thought the original was marvelous. It was a perfect Hitchcock ending. But the studio insisted that they didn’t want to have Cary Grant play a murderer.”
