Factual error: Early in the movie, Mitch is shown walking through a lounge at Harvard Law School. The lounge has multi-colored chairs and couches. It does not exist at Harvard. This lounge is actually the Mark Twain's Lounge in the University Center on the campus of The University of Memphis.
Factual error: Near the end of the movie, Agent Terrence asks Mitch why he didn't release the recording to the media. Mitch replies that it would have been against the law. This is actually incorrect. Tennessee, where the movie is based, is a one-party consent state. Which means only one party needs to give consent to a conversation being recorded. That one party is Mitch McDeere.
