Other mistake: When James Kahn is reading the scrapbook and finds a newspaper article, Anne M. Wilkes is printed in the newspaper title, but a photo to the right of the article shows "Anne C. Wilkes" as the name below the photo.
Other mistake: When Annie forces Paul to burn his new book, she puts charcoal lighter fluid on the draft of his new book. She then adds more to some pages inside the book. The words on the inside page are not a fictional story but a review of the movie Say Anything by Cameron Crowe.
Continuity mistake: During the rainstorm, it shows snow on the roof of the house. The next shot of the rainstorm still has the same amount of snow on the roof - some should have been washed away.
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.
Continuity mistake: When Paul is dining with his agent at the end, after he puts his book down, he picks up a menu. But when the camera angle changes to face him, his hand is empty.
Continuity mistake: When Annie is shaving Paul, she doesn't shave his chin, but, a second later, his chin is shaved.
Continuity mistake: When Paul complains that the paper smudges, Paul types seven letters on a piece of paper to prove it. In the next scene, we see the word he typed was "smudge" which only has six letters.
