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.
Dial M for Murder (1954)
1 revealing mistake - chronological order
Directed by: Alfred Hitchcock
Starring: Ray Milland, Grace Kelly, Robert Cummings, John Williams
Continuity mistake: When Tony throws the 100 pounds down-payment across the room to Swan, watch the chair in which it lands. It has a low back one in one shot, then a high back (probably to provide a bigger target for the throw), then a low back again.
Margot Mary Wendice: Oh, there you are. We thought you were never coming. What have you been up to?
Tony Wendice: I'm sorry darling, but the boss came in just as I was leaving.
Margot Mary Wendice: Tony, this is Mark Halliday.
Tony Wendice: Hello Mark.
Mark Halliday: Hello.
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.
