Revealing mistake: In the first scene, when Nicholson is driving to the Overlook, the shadow of a helicopter can be seen at the bottom right. This is only visible in the un-matted VHS print and fullscreen DVD.
Continuity mistake: At the beginning when Danny is talking to his Mom and eating a sandwich, the sandwich gets about 5 bites smaller in a split second.
Revealing mistake: Wendy has a baseball bat in her hand and Jack is trying to get the baseball bat. When Wendy hits him over the head, the baseball bat bends.
Continuity mistake: While breaking down the bathroom door with the axe, Jack repeatedly strikes and damages the right hand panel, but as he turns away from the door (when he hears the snow-cat) both left and right panels have been damaged.
Visible crew/equipment: In the final shot of the opening sequence (before "the Interview" title shot), at the top of the frame, you will see the helicopter blades twirling. (Visible on fullscreen DVD and VHS.)
Continuity mistake: When Jack breaks the door to the bathroom and reaches in to unlock, Wendy cuts him. Later there is no blood on the knife.
Continuity mistake: In the initial overhead shot of the hotel the hedge maze is not there though later on it is shown quite close to the hotel.
Continuity mistake: In the beginning when Wendy is talking to the doctor, Wendy lights a cigarette, seconds later the paper has burned almost to the filter.
Continuity mistake: When Wendy is looking through all the typed sheets where Jack has typed 'All work and no play makes Jack a dull boy', you can see that they are getting disorganised, and when Jack sneaks up on her, she gets a fright and puts them down in an untidy pile. However, in the next shot, they are in a relatively neat pile again in the tray.
Continuity mistake: When Jack finally dies and you see him lie down on the hedges, his back is flat on the hedge, but when you see him face front, his back is about five feet away from the hedge.
Continuity mistake: When Hallorann is showing Wendy & Danny around after they first arrive at the hotel, they walk through the kitchen towards the camera & into the freezer door to the left of the screen. You can see the kitchen still visible in the background. When they leave the freezer (after Hallorann calls Danny "Doc"), the background is completely different & the kitchen is not visible. This is because they have actually filmed a different door on the opposite side of the corridor. They then walk towards camera again & back into the kitchen they have just walked through.
Other mistake: When Jack Nicholson is talking to the manager of the Overlook Hotel, the manager mentions the death of two girls aged 8 and 10. When Danny sees visions of the two girls they are unmistakably twins, not different ages. A quick look at the IMDb (http://uk.imdb.com/title/tt0081505/fullcredits) proves they are - Lisa and Louise Burns, both born in 1968.
Continuity mistake: As Danny is writing 'redrum' on the bathroom door, the lampshade on the nightstand light is askew. A moment later, when Jack is knocking down the door with the axe, the lampshade has somehow straightened itself out.
Factual error: At the end of the movie there is the chase scene through the hedge maze in the dead of winter in Colorado. While Jack Nicholson runs after his son in a winter setting you cannot see their breath in what would be the cold night air.
Continuity mistake: When Danny is playing alone in the corridor, with his toy cars and trucks, in the overhead shot, the little vehicles are set up on the orange and brown pattern, as the ball roles to him down the center brown path in the carpet's sextagon pattern. However, in Danny's close-up, when the ball is in front of him, all the little toy vehicles are now set up (still the same way) on the opposite side of the carpet's distinct pattern, as he also faces the opposite way. This mistake has absolutely nothing to do with the ghosts of The Overlook moving the ball.
