Continuity: When Abigail runs down the aisle trying to find a hiding place from Shaw and Viktor, she jumps over a small space between some meat display coolers. In that shot the "butcher lady" can be seen behind a large roll of brown paper to the right of the scene. To the left of the space, behind a roll of white paper, is a second butcher. This second butcher is right next to where Abigail lands and is sitting when the first butcher lady says: "If you're not a steak, you don't belong here." But there is no one near Abigail when the camera show her sitting there, talking to the butcher lady.

Continuity: When Ian and Ben are sitting on a couple of barrels discussing what the riddle means, there are a couple of balls hanging from chains very close to Ian's head. A scene or two later, there are a couple of oblong, round, flat bottomed things hanging down next to Ian's head that actually brush against the fur on his hood. Next scene, nothing is close to his head and then the balls come back and then nothing again.

Continuity: When Ben is trying to grab Abigail from Ian's vehicle, we see a bus coming. There is a car on the right side of the bus (Riley's left side) in that shot. We then see Viktor stepping on the brake and Riley start pulling to the left of the bus; when Riley swing around to that side to miss the bus, the car has disappeared.

Factual error: To reveal the invisible ink on the back of the Declaration, Ben and Dr. Chase use pure lemon juice before warming the surface. This is best seen when Chase first test it out on the corner, where the Mason symbol is placed. Lemon juice is in fact also used as invisible ink (that you have to heat to make visible), and this procedure would have ruined anything written on the back of the document.

Factual error: On the back of the Declaration of Independence when the Masonic square and compass are revealed, there is a "G" in the center. This "G" was not used until the period of the Civil War. Confederate Masons refused to use the "G" as they considered it a Yankee trick. Even today the Grand Lodge of England does not use the "G." For these reasons it would be unlikely that the Masonic symbol displayed on the Declaration would have included a "G."

Continuity: When Gates and Dr. Chase are in the store to buy new clothes, Abigail is coming out of the changing cubicle. She opens the door wing while having both hands on the edge, when the shot changes, she leans on the edge with both forearms.

Continuity: When Gates enters the password he has hit the keyboard 4 times "V A (actually the "Caps lock-key, as explained elsewhere) L L" but when we see the screen with the access code, there are only 2 stars hiding the letters.

Deliberate "mistake": In the scene near the beginning of the movie where Ben finds the pipe and finds the message by rolling the pipe on the paper, the message is long and has symbols, but it is impossible for all of that to fit in the pipe.

Continuity: After the Independence Hall chase, Ben tells Abigail & Riley to meet him at the car. When Ben arrives he is confronted by the detective, then placed under arrest, and in the background behind the detective you see Abigail & Riley standing on the sidewalk. In the following shots the positions of Abigail & Riley keep changing.

Continuity: When Abigail keys in her password to the preservation room, she only presses the keyboard 9 times including the return key. If "Valley Forge" was the password, she would have had to have used at least 12 keystrokes (including the return key.)

Factual error: Ben uses SuperGlue to show up the fingerprints on the glass that Abigail was holding. Once the fumes develop the prints they appear as being black, but this is incorrect. SuperGlue would actually make them white.

Continuity: Ben dipped the George Washington button in a liquid solution. But, when he puts it into the gift box, it is considerably larger.

Continuity: In the scene where the FBI storms into Ben Gates' apartment, an agent is researching the Silence Dogood letters on his Hewlett Packard laptop. However, the web browser displayed on his laptop is the Mac Safari browser. HP laptops don't run Mac software so the "photoshopped" shot of the web browser on the laptop was done on an Apple Mac.

Continuity: When Ben and Ian stand at the corner of Broadway and Wall Street, while they are talking to each other, you can see people in the background passing Ben, but they never pass Ian. And, when Ian asks Ben where the treasure is, you can see a black guy wearing a blue shirt passing Ben in the background. 10 seconds later you can see the same guy pass Ben again.

Continuity: When Riley is sitting in the car waiting for Ben, the window is gone and shards of glass can be seen in the window frame, but there has been no shooting yet. Later, the window is back and then it gets hit by a bullet and shatters.

Continuity: When Riley and Abigail are running through the tunnel, trying to get away from Shaw and Viktor, we see Riley running into people and getting knocked around and held up. We see a lady in a red suit go by and then there are two men in suits, the one closest to the camera has a medium brown suit on, over the collar salt and pepper hair and glasses whilst the man farthest from the camera has a medium gray/blue suit on and very short brown hair. The next shot shows Riley trying to go between these two men only now, the one nearest the camera has a very dark charcoal suit on, short white hair and no glasses whilst the other man is wearing a black suit, has greyish brown hair and is much older than before.

Continuity: When we see Ian's men pull up over the grate that they are going to go down through to get to the National Archive, we see the street wet so it had to have rained, been hosed down, etc. But when one of Ian's men drops a large bag down, it whirls up a huge cloud of dust when it lands. This shouldn't have happened because there was nothing over the tunnel but a grate and some water would have gone down the tunnel, wetting the dust.

Continuity: As Viktor is driving the catering van while Abigail is still in the back, we see the windshield get cracked near the bottom left. It gets hit by at least two more things but the next time we see a full shot of the windshield, it is perfect.

Continuity: When they get ready to climb into the tunnel left by removing the coffin, Ian says, "McGregor, Phil. You stay here." When you see the people coming through the tunnel, it's not Viktor and Shaw as you would expect but Shaw and McGregor. Don't know if Sean blew his line, the writers got the characters mixed up or the actors blew it, but something went amiss.

Continuity: When Riley starts down the smugglers' hold his bag is on his left side but when it shows him landing, his bag is now on the right.
