History Film / Suspicion

* AmbiguousEnding: In the end, Johnnie tells Lina that he was intending to [[spoiler:commit suicide]] (rather than to kill her), and that was in Liverpool at the time of Beaky's death (rather than in Paris with Beaky). Lina believes him and makes up with him, but there is no evidence that Johnnie told the truth and, since he is a pathological liar, he could perfectly make it up.

* {{Elopement}}: Lina's parents do not want her to marry Johnnie, so she marries secretly with him.

* HappyEnding: A somewhat controversial one, and implied rather than demonstrated (we don't see Johnnie reform, only ''talk'' like a changed man). In the source novel, Lina is right about Johnnie. He is a criminal, and he is going to poison her with the glass of milk (the novel ends with Lina knowing this and drinking the milk anyway). The book ends with Johnnie apparently getting away with it. One alternate ending considered for the film was for Lina to drink the milk, but not before sending off a letter that exposed Johnnie's crimes. The final ending used for the film has Lina being wrong about Johnnie, with him admitting that he was going to use that poison on ''himself'' rather than go to prison for embezzlement. They elect to face the future together. Hitchcock later claimed that RKO demanded the HappyEnding because they were nervous about Cary Grant playing a villain. Other sources claim that studio memos show Hitchcock was on board from the start with making a movie about a woman's imagination rather than the dark ending of the book.

Remade in 1988 as a UK/US MadeForTVMovie (for Creator/{{ITV}} and Creator/{{PBS}}), with Lina played by Creator/JaneCurtin ([[WTHCastingAgency of all people]]) and Anthony Andrews as Johnny.

* TheCasanova: When Johnnie shows up at a ball, women literally flock to him. Later Lina asks him if he's had a lot of girlfriends, and he admits that he has and said that one time when he couldn't sleep, he tried counting them like sheep.
