Revealing mistake: In the final scene in the belltower you can see shadows from the surrounding trees. That's because this scene was shot at 3 in the afternoon. They just used a filter to make it look like it was night.

1 revealing mistake - chronological order
Directed by: Alfred Hitchcock
Starring: James Stewart, Kim Novak, Barbara Bel Geddes, Tom Helmore
Continuity mistake: Near the end, when Scotty is driving Judy to the Mission, the view from inside the car of the road shows that Scotty is driving on the left-hand side when he should legally be on the right. It is not a one-way road, and it appears that the shot was flipped.
Madeleine: Here I was born, and there I died. It was only a moment for you; you took no notice.
Trivia: The McKittrick Hotel was a very real building in San Francisco. The indoor set was the same one used by Hitchcock two years later in the film "Psycho."

Suggested correction: The McKittrick Hotel lobby and staircase scenes were all shot on location in San Francisco in the Henry F. Fortmann mansion. Proof can be seen in a book about the house in photos taken before it was demolished by Sacred Heart Prep School. The Psycho mansion interiors were all shot on a Hollywood soundstage.
