Continuity mistake: In the treasure vault Riley stands in front of that emerald statue, and on its chest you can see a part which is not covered in dust. In the next shot the whole chest is covered in dust. The clean area coincides with the later placement of Riley's cheek, which means the first shot was actually taken after the embracing and implemented before. (01:50:45)Ronnie Bischof
Revealing mistake: When Ben and Ian get the two different fingerprints from two different people, Mr. Ferguson [random security guard] and Abigail Chase, they are the exact same fingerprints. This can be confirmed on the DVD with pause and zoom. Moreover, the two scans show exactly the same emphasis/pressure on different regions within the print, with more light and detail on the left side and little in the center. (00:39:15)
Continuity mistake: 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 mistake: 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.Sheri Hartman
Continuity mistake: This has to do with Ben getting Abigail's fingerprints off the champagne glass. When he hands her the champagne glass, her fingers are positioned on the lower half of the glass. Later, when Ben "takes" her thumbprint off the glass, he takes it from a much higher part of the glass.
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. (01:12:20)Ronnie Bischof
Continuity mistake: Ben stirs a solution to make the campaign button fluorescent and tests the solution. He dips two fingers into the solution, rubs them against his thumb, then draws a smiley face on the tabletop. When he shines the UV light on the tabletop, there's a small, compact smiley face. But if you watch Ben very closely as he is making the smiley face, he draws the eyes much farther apart and he starts the mouth of the face between the eyes. The one he actually draws is not the one that is shown.Sheri Hartman
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.Twotall
Continuity mistake: When Ian abducts Abigail, you see some one shoot at Ben and hit the hood of his van twice, but in another shot you do not see any bullet holes.
Continuity mistake: 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. (00:22:20)
Other mistake: 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.) And she never goes near the "L". (00:33:20)
Continuity mistake: 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. (01:31:00)
Factual error: In the scene under the Trinity Church in New York, on the wall are two metal support beams in the shape of an X. There are bolts and washers securing the beams. Judging by the elevators that are operated by pulleys, there should be wood with square nails in the time period which the underground passage was built. Seeing the total state of disrepair in the underground elevator shaft, it is extremely unlikely that any updates/repairs were made significantly later than the time it was originally built.
Continuity mistake: When Ben is taking the screws out of the case that holds the Declaration of Independence, the first screw we see him removing is the one in the little "compartment" with an extra little rod across. There are three little compartments with this extra rod across and he is removing the screw from the left-most compartment. Next we see him removing the screw from the compartment just to the left of the previous compartment, but that screw is now back in place. The next time we see him removing a screw, it is again, one compartment to the left and again, the compartment to the right, the one he just removed the screw from, is back in place.Sheri Hartman
Revealing mistake: 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. (00:48:55)
Factual error: When Ben and Abigail and Riley separate at Independence park Abigail and Riley could not possibly have exited the park and run right into the Reading Terminal Market. Independence park (where the liberty bell is housed) is between 5th and 7th and Walnut Streets, and Reading Terminal Market (where Abigail hides from the bald man) is at 12th and Arch street. At least 15 blocks apart.Boobra
