Revealing mistake: In the opening scene when Brandon opens the curtains to let the light in, he is suddenly casting a shadow on to the couch, towards the window, as if the light is coming from behind where the camera is located. (00:04:15)
Rope (1948)
1 revealing mistake - chronological order
Directed by: Alfred Hitchcock
Starring: James Stewart, Farley Granger, John Dall, Dick Hogan, Edith Evanson
Continuity mistake: When David is killed in the very first scene, the two men lay him neatly in the big chest, the rope does not hang out the side. But then one man bends over and discovers the rope halfway hanging out of the side of the chest. Plus it was knotted around David's neck anyway, so couldn't have been yanked out, it would have had to be untied.
Brandon: The good Americans usually die young on the battlefield, don't they? Well, the Davids of this world merely occupy space, which is why he was the perfect victim for the perfect murder. Course he, uh, he was a Harvard undergraduate. That might make it justifiable homicide.
Trivia: This was the first film in colour directed by Alfred Hitchcock.
