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.
Suggested correction: This sort of discontinuity is deliberate. The layout of the Overlook is intended to make no sense.
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. (01:32:40)
Suggested correction: This along with other subtle movements and the microscopic misplacement of everything inside the Overlook is meant to snap back to its former or appear "off" for no reason other than it gives the viewer an uncomfortable and uneasy feeling.
Other mistake: When Stuart Ullman is showing Jack and Wendy their quarters, there is a window on the wall to the right across from the bed. However later, when Jack tries to break into the bathroom with the axe and Wendy puts Danny through the window onto the hill of snow, their quarters is not on a corner of the hotel, which the aforementioned window would suggest. (00:22:45)
Suggested correction: Stanley Kubrick intentionally did this, to get the audience to feel like something has been off the entire movie. Like in the interview scene, there should be a hallway where the window is but there's not. And the hotel is constantly changing itself as it is sentient.
