Visible crew/equipment: While Tony is blackmailing Charles Swann, describing the story in the newspapers regarding the "middle-aged woman found dead due to an overdose...", just as Tony takes a seat on the table we can see the moving shadow of the boom mic on the wall, over the picture. (00:25:10)
Dial M for Murder (1954)
1 visible crew/equipment mistake - chronological order
Directed by: Alfred Hitchcock
Starring: Ray Milland, Grace Kelly, Robert Cummings, John Williams
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.
Mark Halliday: What is all this?
Chief Insp. Hubbard: They talk about flat-footed policemen. May the saints protect us from the gifted amateur.
Trivia: This was filmed in 3-D, but was not originally released in 3-D. It wasn't until after Hitchcock died that it was released in its original 3-D form.
More questions & answers from Dial M for Murder
Chosen answer: It's mostly so the audience can see more of Tony's underlying character. This is Margo's bed, and Tony wanted it separate from the bedroom that they shared as husband and wife. Tony is "emotionally divorcing" himself from Margo as he is about to start a new life as a single man. Leaving the bed in the bedroom would serve as a reminder of his guilt in framing his innocent wife for a murder she did not commit. The bed is likely parked there until he can get rid of it.
