Visible crew/equipment: Three times you can see lens flare as the camera is pointing towards the sun: the airborne-shot of the Jefferson Memorial (in this one you can even see a part of the airplane or something else in the lower left corner), the Philadelphia skyline as they drive into Philadelphia, and the view from the "target location" of the shadow of the cross (near the brick containing the glasses) towards the steeple with the bell.

Factual error: When Ben and the rest of the group start to climb under the church, Ben moves some spider webs out of the way with his torch. The dust on the spider webs would have burst into flames when he did this, but instead they just fall to the side.
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.
