Factual error: All the light switches are the wrong way round for UK, where up is off. Presumably because film sets were in USA.
Suspicion (1941)
1 factual error
Directed by: Alfred Hitchcock
Starring: Cary Grant, Nigel Bruce, Cedric Hardwicke, Joan Fontaine
Continuity mistake: Johnnie, Lina and Beaky are playing anagrams. Lina spells out the word MURDER with an M as the first letter. The shot cuts away and then back again, and now the first letter is an inverted W. (01:01:40)
Isobel Sedbusk: I always think of my murderers as my heroes.
Trivia: Hitchcock had two cameo appearances in the movie Suspicion: the first takes place right after the opening scene where Johnnie and Lina meet on the train, when Johnnie and friends are gathered for a 'photo op' just prior to the start of the 'hunt'. You see Hitchcock shortly after that scene walking with a horse past the camera. He is to the left of the horse and is wearing a cap and light colored jacket. The second cameo shows Hitchcock, albeit from a distance and not easily identifiable and ever so briefly, posting a letter at a mailbox in town.
Question: Was Lina supposed to open the necklace box when Johnnie gave it to her on the patio with the other gifts from the horse race? She tries a few times and can't.
