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. (00:01:05)
Continuity mistake: When one of the stormtroopers unties Han Solo before he is put into the carbonite, watch his wardrobe - he has a disappearing / reappearing jacket on. This is fixed to an extent on the DVD - the jacket is now lightened to almost match his shirt, but it's still shiny like leather. (01:32:05)
Suggested correction: It just looks like a jacket because it's a shadow.
Continuity mistake: There are a couple of instances in the movie where the models do not correspond with the actual sets. When Klytus arrives at the Hawkmen city he lands near the top of the city. Yet in that very hall there is a pit with a deep void underneath. Such a room could only exist at the bottom of the city. Also, when the Hawkmen start to land on Ajax, its engine section appears to be missing. (01:10:10 - 01:14:30)
Continuity mistake: While Father Malone is drinking his wine you can still see the cork laying on the table. He finally gets up to try to catch Bennett before he leaves and the cork has mysteriously put itself back into the bottle. (00:05:00 - 00:05:45)
Visible crew/equipment: After they've killed the snake, Alice says "Is it dead?" and as the camera pans up, the boom mic's shadow is visible moving across the wall, directly over Ned's head and the red box. (00:26:05)
Continuity mistake: The roof of the Chessman House changes, going from having a middle roof to no roof in the middle.
