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.

Continuity: At the Charlotte down in the cargo hold when Ben has just figured out that the riddle refers to the Declaration of Independence, Ian's stocking hat keeps changing between scenes. He's got a two-toned hat with a jagged edge between the two colors. Sometimes, the edge is turned up so far you can't even see this design. At other times, the edge is barely turned up and crooked and the jagged edge between the colors is very prominent.

Continuity: When Ben is in the Men's restroom taking off the overalls to reveal his tuxedo, he is in front of the third or back sink. He turns, throws tool belt away, turns back toward mirror and grabs his drill and starts to leave with the red NO SMOKING sign on the mirror up to his left. Then he stops to look in the mirror again as Riley says "How do you look?" He is looking into the mirror straightening his tie and the red NO SMOKING sign is on his right. The next frames he is back in front of the third sink smoothing his hair back and the NO SMOKING sign on his left.

Continuity: When Ben is at the Keypad ready to enter the password. We hear him read out the letters that where pressed by Abigail earlier. He reads out the letter L, but earlier when we see Abigail type the security code onto the keypad, she never presses the letter L.

Continuity: In the scene where Ben and Riley meet Abigail for the first time, Abigail's assistant ushers them into the office and the camera shows her walking out of the office. In the next shot you see the camera on Abigail talking to the two men. When the camera pans back to them, you see the assistant leaving the room again.

Other: When Gates writes down the numbers from the back of the Declaration of Independence he forgets one number. On the document there are the following numbers: 11-6-6, 12-18-7, 14-3-7. Ben however only writes down 11-6-6, 14-3-7 and then keeps on.

Revealing: When Ben, Abigail, and Riley are fleeing the National Archives, the window on the driver's side has been shattered by a gunshot. Although they are driving at high speeds, no wind seems to be entering the van to mess up their hair.

Factual error: When Ben finds Charlotte buried in the ice, he would have encountered solid, thick ice. The small pick-ax he uses seems to easily break through the ice. Also, he seems to be digging through packed snow, rather than thick ice, which is indicative to the Arctic ice shelves.

Factual error: As a librarian, I was amazed that the main characters in the movie time and time again touched the document without gloves. The oils on their hands would have caused this old document to crumble.

Continuity: When Ben is first confronted at his father's car by the FBI, you can see Chase and Riley in the background standing there and then turning around and leaving. Then as they arrest Ben against the car, you can see Chase and Riley just turning the corner, noticing Ben being arrested, and leaving.

Factual error: In the scene in the Charlotte, the black powder would never have exploded after being buried in ice for 200 years. It also would not burn without creating enormous amounts of thick grey smoke.

Continuity: Near the beginning of the movie when Ben, Ian and Riley are in snow CATS and we see Riley's computer screen, viewed a little from the left, and there is a jiggling hula dancer, supposedly mounted on his keyboard surface. In the background, a window has popped up showing the location and route of the two CATS. Then we hear alarm go off and we see almost the same shot but a little closer in on the computer screen. The hula girl is missing. The difference in angle and "zoom level" could not account for not seeing the hula girl in the second shot.

Continuity: When Dr. Chase is entering her password she goes for the first letter on the keyboard. Her little finger is at the right end of the space bar and her index finger is hitting the key. When the shot changes to the close-up of her hand, the little finger is in the area of the CTRL key and the middle finger is the one which hits a key, in the area of the m or comma key.

Continuity: When Ben finds the glasses at Independence Hall, it is 3:20 because of daytime savings time. However when the bad guys chase Abigail and Riley in the market they pass a large clock showing the time to be 2:37.

Continuity: When the two vans are driving away from the Archives, Dr. Chase tries to open the door to escape. As the camera pans from her face to the door handle, you can see by the way her hair moves that the quarter-second sequence is run in reverse.

Continuity: As Ian watches our heroes leave Independence Hall the clock in the tower reads 3:27. That gave Ben only five minutes to climb down the tower, dig out the brick, meet up downstairs, unroll the Declaration and decipher it, realize they're being followed, plan their escape and leave. It took me longer to write all of that.

Continuity: When Gates and Riley are talking in front of the Lincoln Memorial, the clouds in the background change. It would be possible that they change so quickly during the shots, but only if there was a gale and not sunny weather as it is in the movie.

Other: When Gates enters the password to enter the preservation room he accidentally hits the Caps Lock key instead of the "a" key.

Factual error: In the scene when Ben, Abigail and Riley are on the tower of Independence Hall, they look at the shadow marking the secret place where the glasses are hidden. It is 3:20. The shadow of the cross is in the second third of the pillar. When Ian is on the tower the shadow has already moved to the top of the wall. As the others have left Independence Hall at 3:28 the shadow must have traveled the distance in about 4 minutes. This is far too quickly.

Continuity: The school boy is counting letters on the Dogood letters and runs out to give them to Riley. As he crosses the street, he passes a cab and a Taurus station wagon. On his second trip out, he passes the same two cars again.
