Rear Window (1954) - 11 mistakes

Continuity: There's an oscillating fan near the ceiling that alternates between running and not running from one cut to another in one scene.

Continuity: When the nurse first visits Jefferies, his hands are separated. They jump together in the next shot when she places the thermometer in his mouth.

Continuity: After James Stewart's second massage, he buttons once in the middle of his pyjama shirt. In the next shot the top button appears buttoned as well.

Continuity: Jeff has just fallen from the window and is lying on the ground injured. The detectives who broke his fall are next to him as Nurse Stella rushes up to help. Lisa is still across the courtyard, running to him, but in an instant, she is sitting on the ground, her legs tucked under her with Jeff's head resting in her lap just as Stella begins to attend to him.

Continuity: When Jimmy Stewart is watching the couple in the next building, the wine glass behind him alternates between being almost full and almost empty in successive shots.

Continuity: When Miss Lonelyheart brings home a younger man, she slaps him on the left side of his face, but when he leaves and stands outside her door, he rubs the right side as if it hurts.

Continuity: When a man carrying a big block of ice passes by the sculptress's backyard, we see her cat sitting on a chair next to her as she works on her "Hunger" sculpture. In one shot, the cat is facing toward the man, and in the next, it is facing away him when it gets up, turns around, and meows at him.

Continuity: James Stewart uses a camera flashgun to defend himself by repeatedly temporarily blinding Thorvald in the closing scene. The number of flashbulbs in the cardboard box drops by two between cuts as Stewart wheels himself back away from Thorvald.

Revealing: In the shot of the helicopter hovering above the apartment building, the blue screen technique is needlessly revealed by the eratic and physically impossible movements of the chopper. This could have been avoided if the camera shooting the aircraft had been stationary. It appears, however, that it was a handheld shot.

Revealing: At the end of the movie, when Jimmy Stewart is hanging in the window, we can se that it's a stunt double.

Continuity: If you look carefully, you can see that the apartments of Miss Lonelyheart and the Thorvalds appear to be ridiculously small in depth.
