Continuity: When Humbert and Charlotte Haze discuss sending Lolita to a girl's camp, Charlotte holds a smoking cigarette in her left hand in some shots, but not others.
Continuity: When Humbert comes through the door in the beginning of the movie, he walks by a painting in the hall. Some moments later he is shot through the same painting on the stair case. When Quilty is first shot in the leg, a covered chair is visible at the top of the stairs, it isn't until Humbert reloads and Quilty makes it to the top of the stairs that we see the painting that he hides behind before being shot.
Crew or equipment visible: There is a moving shadow of crew member on Humbert's back when he is talking to Lolita in the kitchen of her house; the same movements can be seen directly in crew member's reflection on the television screen facing the camera.
Crew or equipment visible: Director Stanley Kubrick. walks through very first shot (center to right bottom) of Humbert in Quilty's house
Boom mic visible: When Humbert urges Mrs. Richard T. Schiller to leave her husband and return to him, the shadow of the boom mic is visible on the back wall.
Continuity: The car Humbert parks at the service station has a lamp attached to the front grille, and carries number plate 17459. A few minutes later when he has the blowout (which seems to leave all four tires intact) the lamp is missing and the number plate reads AC629.
Continuity: A bottle seen standing on the piano bench in Quilty's house is no longer there when Quilty sits to play at the piano.
Revealing mistakes: As Humbert Humbert and Dolores race to escape the car that HH believes has been tailing them for three days, their own car sustains a puncture (blowout) and HH has to slew the car to a halt. The low camera angle at the front of the vehicle, however, shows all four tyres fully inflated and all four corners of the car riding at normal height above the road surface.
Continuity: When the blow out happens, the shots immediately afterward show the car is on a long, straight stretch of road. However, in the shot immediately before this, Humbert was steering the car through numerous corners, and had only just finished straightening the car out when the blow out happened.
