Factual error: When Ben, Abigail, and Riley are discussing the correct time to be at Independence Hall, they would need to know the exact date, not only the time, of the painting to be sure to see the correct shadow.
FBI: Here are your options. Door number one you go to prison for a very long time, door number two you help us get back the declaration from Ian, and you'll still go to prison for a very long time, but you'll feel good inside.
Ben Gates: Is there a door that doesn't lead to prision?
FBI: Someone's gotta go to prison, Ben.
Trivia: When Ben is talking to Riley in front of the Lincoln Memorial, you see a long pool behind them. This pool is filled with computer generated water, because the pool was drained at the time of shooting.
