At the end, Ben is writing the article. There is an error in the text. It reads, "He was a cop, she was a judge, and they had all the resourced necessary to paper the adoption without raising any suspicions." The word "resourced" should actually read "resources".
When the envelope is slid under Ben Shepard's door, the attached paper is neatly stapled to it. When the camera zooms in, the paper is askew. When the camera zooms out, the paper is neatly attached in the corner again.
An Esso gasoline sign is clearly shown in the movie, which supposedly takes place in the United States. However the Esso brand was replaced in the U.S. by Exxon in 1972. The Esso brand remains in use outside of the U.S.
In the closing scene a trolley bus passes by as Sloan and his daughter are walking. The scene was supposed to be in Detroit or possibly New York. Neither has trolley buses, but Vancouver, where it was filmed, does.
The packet of information about "James Grant", derived from his Social Security number, includes a U.S. Passport issued to "Jim Grant." U.S. Passports are always issued based on the person's full name.
One sequence takes place at "Bureau of the State, Department of Licencing". In New York State, where the scene is set, there is no such entity as "Bureau of the State - Department of Licencing" -- the corresponding government office in actuality would be The New York State Department of Motor Vehicles, where drivers licenses are obtained. Moreover, "licencing" is British spelling -- something that you'd never see in an official context in the U.S.
A U.S. Passport is shown as having been issued to Jim Grant on February 13, 2003, with an expiration date of February 13, 2013. U.S. Passports expire in exactly ten years, so the correct expiration date would have been February 12, 2013.
Throughout the film, the characters (who are now established professionals in their fields) are constantly saying "Off the Record" and we see Ben Shepard either agree or, better yet, turn off his recording device. This is pure fantasy and no professional would think that telling a reporter ANYTHING is, "Off the Record." At one point, Shepard even remarks, "Those are the rules" which is (at best) the closest to real life; an unwritten rule with no basis in fact or law. No professional (Retired Chiefs of Police, University Professors, Attorneys, etc) would ever discuss such information with the belief that what they are saying won't be used and/or quoted.
Jim Grant's Volvo plate TRI-19H4 is incorrect. At the time of this movie, NY passenger plates were issued with 3 letters and 4 numbers unless they were special registration plates (SRF, chosen by the vehicle owner). If they were SRF, the characters would be together with no hyphen between any characters.
