Goofs

The train carrying Uncle Charlie to Santa Rosa at first has a number 140 on the side and on a tag in front. As it pulls into the station, the front tag has disappeared, and the number on the side has changed to 142.

When the detective brings young Charlie home, her father and his friend can be seen walking around the veranda, but young Charlie meets them along the garden path.

When Charlie is leaving the bank president's office, Mr. Green is in the background standing behind his desk. He is striped with Venetian blind shadows and his chair has a low rounded back. A moment earlier, a closeup of Mr. Green shows no such shadows, and his chair has a high squarish back.

When Charlotte and Charlie cross the street to go to the bank, the street corner is empty. In the next shot, there are many people on the same corner.

In the beginning of the film, when the landlady enters Uncle Charlie's room, he is lying on the bed with his hands crossed on his belly holding a cigar. For a moment he appears with his hands and the cigar on his chest.

Still believe that this house was much to big for a simple bank clerk. Good for a bank manager though.

Uncle Charlie calls Western Union from his hotel room and has them send a telegram. When it arrives, the telegraph office calls the home of the recipient and reads it to them. Who paid for the wire and how? In the 1940s, and as late as the 1970s, it was normal practice among stores and service providers to run revolving accounts for local residents. The family would be billed on a monthly basis for services or goods purchased since last billing.

When Ann is talking on the phone to Mrs. Henderson, Ann doesn't give Mrs. Henderson any time to speak; she just rushes on to her next line.

Near the beginning of the movie, Ann answers the phone when the telegraph office calls. She delivers all her responses without pausing long enough to allow the caller to respond.

While Charlie watches the cab take her family to Uncle Charlie's speech, the shadows of crew members are visible against the bushes in the background.

When young Charlie is reading the newspaper in the library, the camera casts a shadow on her back.

When Young Charlie finds she's locked in the garage with the car's engine running, she might reasonably have gone back to the car and broken out through the door with the car driven in reverse.

Note: Charlie is simply trying sabotage to kill Young Charlie in any way he knows (fixing the stairs etc which also fails). Simply being sabotage each way wouldn't guarantee a fatal outcome but he just keeps trying - though as an accomplished strangler (of women) it is a plot hole that he doesn't just do that to her instead. Maybe he only strangles elderly rich widows like in the rest of the movie though.

At the beginning of the movie at the boarding house, the money on the floor and on the nightstand are 1915 one peso notes from El Estado de Sonora. Since Charlie intends to contact Uncle Charlie in Philadelphia via telegram, why would he have a bunch of Mexican money which even Mrs. Martin, his landlady expresses concerns about?
