Revealing mistake: During the big fight scene, just as Annie Wilkes falls to the floor and hits her head on the typewriter, the actress is replaced by a really bad looking Kathy Bates dummy!
Revealing mistake: When Paul goes through Annie's scrapbook, a fast reader may notice that several newspaper clippings (although having different headlines and being based on separate events), have the exact same story underneath. The text has simply been repeated, rather than a new report being created for each story.
Revealing mistake: When Paul and Annie are getting ready to tap glasses, you can see Annie deliberately knocks over the candle. She moves her hand right into the candle to make it fall over.
Suggested correction: It is implied, though by no means certain, that Annie may have intentionally caused the glass of wine to spill, especially as at this point she already knows Paul has been out due to the direction of the Penguin figurine.
