Factual error: When Gates is talking to Ian under the Trinity Church, he says that Thomas Newton placed the lantern in the Old North Church to signal how the British were coming. However, it was the Church sexton, Robert Newman, who actually placed the lanterns. Even though Ian probably wouldn't know the difference, surely three historians (Patrick Gates, Ben Gates, and Dr. Chase) would have known the correct person in so important an event in American history. There was no reason to throw Ian off track by saying this, since he didn't even know how many lanterns were placed.

Continuity mistake: When Sadusky has Ben handcuffed across the desk from him, there is nothing on the desk directly between Sadusky and Ben except Sadusky's coffee mug, a gray thing that is about mid-way between Ben and Sadusky, and a white spiral notebook to the right of the coffee mug. Then Ben says, "Ian still ended up with the Declaration of Independence," and as the shot switches from Ben to Sadusky saying, "Because of you," we see the glasses Ben found at Independence Hall appear on the desk in front of Sadusky between the gray thing and himself. Then as Sadusky says, "Someone's got to go to prison, Ben," and Ben says, "Yeah," two short stacks of papers appear on the desk in front of Sadusky and the glasses changes position as well.

Continuity mistake: This concerns National Treasure 1 and 2. In the first film, when Ben's grandfather tells Ben the story about the clue given to Thomas Gates, he says he was the grandfather's grandfather's, grandfather - Ben's Great, great, great, great grandfather. In the film, in 1832, he appears very young, maybe early 20s. But in the second film Thomas Gates, Ben's Great, great grandfather, appears to be 40-50 in 1865. A young man in 1832 can't have a middle aged grandson in 1865.
Factual error: In the scene under Trinity Church, Ben is holding on to the elevator and trying to get a grip to swing to safety (after Dr. Chase is already to safety). He grabs a board that falls off, then the last board pulls back an is shown to be held on with modern day nails. If it were built 200 years before, as the movie suggests, these would not likely be the kind of nails from the local hardware store as shown in the film.
Continuity mistake: When Ben is trying to pay cash for the 'replica' of the Declaration of Independence in the Gift Shop, he lays his wallet down on the counter and starts counting out bills and change right next to his wallet on the counter. A few scenes later, when the FBI is reviewing surveillance tapes, one of the monitors shows Ben reaching in his pocket, pulling out his wallet and grabbing the money that is out on the counter. This happens when the over voice says, "Charge. Benjamin Gates."

Continuity mistake: In the catacombs under Trinity Church, the lift Ben and Abigail are standing on falls. When it jerks to a stop, Abigail falls and Ben catches her. The lift is stationary at an angle. However, in the next shot, the lift is swinging forwards, allowing Ben to throw Abigail to safety.
Factual error: When Riley is sitting outside the Franklin Institute and sees the ad on the side of the bus with the close up of the Liberty Bell, the SEPTA bus is labeled with the 108 Airport route. That bus route goes from the 69th Street Transportation Center to the Philadelphia International Airport and would not pass near the Franklin Institute.
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.
Other mistake: In the scene where Ben, Riley, and Abigail arrive at Patrick's house, the location title at the bottom of the screen says, "Philadelphia, PA." Then, as the Declaration of Independence is being examined, Patrick says that he donated the Silence Dogood letters to "The Franklin Institute in Philadelphia." Finally, as the scene ends, Ben, Riley, and Abigail are in Patrick's car, driving through the night towards Philadelphia.
Other mistake: When Ben enters the Gala dressed in overalls and tool belt, he enters a door across the street from where Riley is parked. There is a security guard outside that door who waves Ben on into the building. As Ben exits that same door, there is no security guard, which seems hard to believe with such a big event.
