Continuity mistake: When the crime bosses meet up at the casino, in the exterior shot, there are a few items on the desk including a bottle, an ash tray, a plate with a slice of pizza and a newspaper. Later, when Batman appears and punches one of the crime bosses onto the table, the bottle, ash tray and plate have suddenly moved closer to the newspaper. (00:02:00 - 00:02:28)
Continuity mistake: When Harrison Ford is on the rooftop and the suitcase accidentally opens, the Statue of Liberty goes flying off the rooftop and on to the ground, several stories down. In the next shot, the little statue is perched at the edge of the rooftop. Also, the clothes that fly away magically reappear next to the suitcase a shot later.
Revealing mistake: The overhead shot of Grohman climbing down the mountain features an alpine stuntman wearing gloves, while at no point Mario Adorf was shown wearing any. (00:50:20)
Continuity mistake: After Redmond is killed, when the flashback starts, Leonard's back is to the main door of the cabin. When the flashback is over, his back is to the kitchen.
Continuity mistake: The car the hybrid man pushes is in OK shape at first, then he lifts and flips it through the copper fence, and now its whole front side is gone. They might used an already wrecked "car double" for the scene when it crashes and explodes. (01:40:50)
Continuity mistake: Throughout the scene where Roland and Maud are sitting on the floor looking through the things in the box from Ash's grave, the head of Maud's hairclip switches constantly from one side of her head to the other.
Visible crew/equipment: In the scene near the start of the movie when Lois Chiles is showing Mia Farrow her bathroom and Mia Farrow is saying "Yes, It's lovely," on the mirror on the right you can see a member of the crew crawling around on his hands and knees. This is visible on the DVD as well as at the cinema. (00:05:50)
Continuity mistake: When Renée Zellweger drives up in front of her house the first time in the movie, as she shuts her car off, her window is down. When she gets out, the window is back up.
