Other mistake: The first time we see George Loomis back at the Rainbow Cabins after his supposed death he's by the garbage cans in the back of cabin B with a brick wall on the left. The next time we see him two shots later the film has been reversed with the brick wall now being on the right. (00:46:45)????
Other mistake: The Cutler's now occupy cabin B at the Rainbow Cabins and just before we see George Loomis by the garbage cans in the back of the cabin Polly decides to take a nap. When she gets up from the bed to close the Venetian blinds we see the pillow case and it's white, but two shots later after the blinds are closed she lays down again and the pillow case has a huge dark make up stain on it from several previous takes. (00:46:20)????
Continuity mistake: Marilyn walks up to the ticket booth and gets a refund for one of the tickets to Chicago that she bought earlier in the movie. Looking at her luggage we see no marks on it at all. She picks it up the same way she puts it down, but in the next shot a large black mark appears on the front of it. (01:01:15)????
Continuity mistake: As Polly Cutler lays out on a beach chair sunning herself Ray steps back and decides to take a picture of her sitting there. Niagara Falls, which are always seen behind them are not in this shot, which has obviously been filmed on a sound stage. The bushes against the stone pillar are also different. (00:34:55)????

Factual error: Marilyn and the Cutler's follow Inspector Starkey down to the bottom of The Scenic Tunnel Trip to identify George's shoes and when they come up Marilyn hears the song "Kiss" chiming from the bell tower. This is an obvious mistake as the shot of the bell tower that we see here is taken from the American side of the falls and The Scenic Tunnel Trip is on the Canadian side of the falls. (00:39:55)????
Continuity mistake: Several dark marks appear then disappear and then reappear at different times on the Loomis's front door to cabin B. The marks are there during the party when George Loomis storms out and breaks the record, but then they're not there as Marilyn walks back into the room after speaking to the Cutler's. (00:36:05)????

Continuity mistake: In the very first scene of the movie Curly looks at the pictures of his wife that Jake took. He gets to the fourth picture and rotates it 45 degrees to get a better look. As he goes on to the next picture he lifts the fourth one up, and in the next shot he's holding a different picture. (00:02:00)????
Continuity mistake: As Marilyn walks into room 7-A of the City Morgue to identify her husband George she's carrying her pocketbook in her right hand. After she sees the body she faints and falls to the floor but we never hear the pocketbook hit the floor because it has been neatly placed next to her before she fell. (00:42:05)????
