Directed by: Alfred Hitchcock
Starring: Robert Donat, Lucie Mannheim, Godfrey Tearle, Madeleine Carroll
Continuity mistake: In the apartment when Hannay discovers the dead women the telephone changes from white to green.
Suggested correction: The film is in black and white. How can you tell what color the phone is? We're you watching a colorized version? Or did you mean to post this on one of the remakes?
Continuity mistake: Hannay is talking to the milkman inside the door. Outside the door you can see across the street, the two guys walking down the sidewalk. A moment later, Hannay goes toward the door and now there's the milk wagon on the street right in front of the door. When Hannay pointed out the two guys across the street to the milkman, the milk wagon wasn't there and the milkman is inside with Hannay so he couldn't have pulled it up.
Heckler in Audience: How old is Mae West? How old is Mae West?
Trivia: Director Alfred Hitchcock has a cameo role in this film - he is seen tossing some litter as Richard and Annabella run from the music hall.
