There are two different versions of the "Mary Shaw" poem. In the movie the poem goes, "Beware the stare of Mary Shaw. She had no children only dolls. And if you see her in your dreams, do not ever, ever scream." On the trailer it was, "Beware the stare of Mary Shaw. She had no children, only dolls. And if you see her do not scream, she'll rip your tongue out at the seam."
When Detective Lipton confronts Jamie in the hotel room after Jamie tries to bury the doll, there are several occasions when Lipton's mouth does not match the words being spoken between cuts or isn't moving at all.
