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: During the demonstration with the billiard balls as 'Indians', the balls are placed differently on the table depending on the take. (00:37:00)
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: After Willis rescues the people, he's at breakfast with his son and wife. He slides the newspaper to his son. Close-up on paper (beside orange juice) shows "Bold" typestyle on story slug. Camera pans up to Willis, cuts to son, cut back to newspaper. Suddenly typestyle is italicised (noticeable on "f" in "found"). (01:34:30)
