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.
National Treasure (2004)
1 visible crew/equipment mistake
Directed by: Jon Turteltaub
Starring: Nicolas Cage, Christopher Plummer, Sean Bean, Harvey Keitel, Jon Voight, Diane Kruger, Justin Bartha
Factual error: As Ben is clinging to the staircase while it is falling apart, there is a close-up of a nail being pulled out of the wood. This nail is round-headed, rather than square as it would have been over 200 years ago. It's also shiny instead of rusty, which indicates that it's galvanized. Galvanization as an industrial, metal-preservation process was not patented until 1837, and was not used in building materials until well into the late-1800s. Since the film states the staircase was made by "the Founding Fathers, " and there was no galvanization of iron nails in any industrialized nation in 1780s-1830's, this is a huge anachronism.
Riley Poole: Asuming Ben's theory is correct and my tracking model's accurate, we should be getting very close. But don't go by me, I broke a shoelace this morning. It's a bad omen.
Ian How: Should we turn around and go home?
Ben Gates: Or we could just pull over and throw him out here.
Riley Poole: Ha, ha, ha, okay.
Ben Gates: Well Riley, you're not missing that small, windowless cubicle we found you in are you?
Riley Poole: No, no. Absolutely not.
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.
