National Treasure (2004)

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: The interiors of the ship Charlotte were filmed inside the Union Ice Company in Los Angeles to give the scene a more realistic feel. Also, the crew from the Charlotte was dressed in costumes borrowed from The Pirates of the Caribbean; The Curse of the Black Pearl.
