Corrected entry: Early in the film, Grace Kelly is talking to Bob Cummings about their extra-marital relationship and blurts out "Oh, Bob." even though Bob Cummings' character's name is "Mark Halliday."

Correction: I think it's Grace Kelly's accent that just sounds like she said "Bob" but she actually did say "Mark".


Correction: Tonight, I heard "Bob" for the first time. Then I checked the CC. Nothing. I played it back a couple of times: "Bob." And then I played it with my eyes closed-just listening, and it sounded like it could be "Mark." But since I wasn't thinking about it when I heard it the first time tonight, I'm leaning towards "Bob."

She does say "Mark." You can hear the "mm" at the beginning. She doesn't have a hard "k" sound at the end though, she has a very soft "k" sound like she did at the end of the word "drink."


Corrected entry: Near the end of the movie, when Tony leaves to go to the police station and retrieve his wife's belongings, he rushes out of his apartment, pulling hard on the door so it shuts itself and keeps on moving, leaving the apartment building. He never stopped to lock it. This is an important mistake because the whole point of the key business at the end is to determine if the police inspector can get in with the key he has in his possession. The door isn't locked, yet the inspector uses the key he has in the door, goes inside the apartment, phones the police station to tell them he got in and to "start the ball rolling," meaning now it's confirmed the key he used unlocked the door...the door Tony hadn't locked.

Correction: It is common in Europe (the film takes place in London in the 1950s) to have apartment doors which lock automatically. You have to use a key to get in again, even if you hadn't previously turned the key once or twice in the lock to secure the door for good.That kind of device is usually called a snaplock. When Grace Kelly stands in the doorframe saying goodbye to Ray Milland and Robert Cummings who are going to a stag party, you can see that the door has no knob or handle on the outside (which is typical for snaplocks).

Corrected entry: After the trial, Chief Inspector Hubbard visits Tony to execute a complicated ruse that he had prearranged with Sergeant O'Brian (at the station) and Detective Williams (stationed upstairs). The ruse relies on the inspector mentioning Margot's handbag and switching raincoats with Tony. The inspector would have left the apartment without doing either of those things had it not been for Mark being present and calling out to the inspector, but the inspector would not have expected Mark to be in the apartment.


Correction: We do not know that the Inspector did not have some other plan to do these things, to come back some moments later for example. He could have just taken advantage of Mark's appearance.

There are an infinite number of things in any fictional movie that we do not know. It's possible to make up alternate facts to suit an alternative plot line - but that would be a different movie. My plot hole does not rely on an alternative that the inspector did not express.


Revealing mistake: Just before Anthony Dawson is going to be stabbed to death by Grace Kelly with a pair of scissors, you can see for a very short moment that the scissors are already attached to his back.
