Continuity mistake: Agatha opens the restroom door form the outside and it opens inside to the left. The inside view of the restroom shows Agatha opening the door to the right.
Factual error: Muñoz's name is misspelled on his headstone as "Dr. Juan Munos," omitting the tilde and changing the z to an s. (00:02:15)
Visible crew/equipment: In the 1920s, Agatha takes a taxi to Muñoz's house. In the background, through the taxi's rear window, you can see a large white 1970s Universal Studios panel truck being loaded next to another building on the back lot. (00:02:45)
Continuity mistake: During Juan and Agatha's dinner together, the camera circles them, passing behind Juan (where an "invisible" cut occurs) and continuing to move left around the table. Between the two segments, the position of Agatha's hands changes noticeably. (00:11:50)
Visible crew/equipment: When the landlady opens the glass-paned door, it reflects a large, round studio light. (00:04:10)
Continuity mistake: While she talks to Mrs. Gibbons on the stairs, Agatha's paper sack changes its position and appearance several times between shots. (00:16:15)
