Other mistake: During the scene where Phil and Claire break into the real estate office to look up the name of her past client, Claire says his name is Holbrooke Grant. She types that into the computer to search for it, but it's shown as Holbrooke, Grant. With the comma, that would make Grant his first name.

Other mistake: There's a scene at the end of the movie where Annie is sitting looking through some graduate school brochures, and her boyfriend Hayden comes over and hands her a letter from the "5th Avenue Mom" she used to work for. She says she can't read it so he offers to read it to her. The camera shows a close-up of the letter as Hayden starts to read. In the letter it's written that it's been "some time" since we've spoken, but he reads it as "several months."
