Other mistake: Several close-ups of the business cards of Patrick Bateman and his associates reveal a misspelling of the word "Acquisitions" (the "c" is missing - not a small error, given that this is the name of their department).

The donor bag is rear-facing when he drops it, but in the close-up it's front-facing to show the words "human organ for transplant", and its straps positions also change between all shots. (01:07:00)

Revealing mistake: As Elsa sings "Let It Go" she pulls her hair into a long braid going down her back. She pulls it with her left hand from behind her to in front, but the end doesn't flip over her shoulder, she just pulls it straight through to the other side without going over the top. (00:34:10)

Continuity mistake: In the scene where Owen and Tom pull Dodger from the pool. We see that Dodger's hair is hanging down over her face. We then see Owen's reaction, and then we return to Dodger.
