Continuity: In the scene where Bourne is talking to Firsch, the gun he is holding changes from a Glock in the shots where the camera is looking at Bourne, to a SigPro when the camera is looking at Firsch.

Visible crew/equipment: Many shots when they are in the CIA building, you can see the cameraman in the glass walls.

Factual error: When Jason Bourne travels to Madrid to catch Daniels, there is a minor shot where an Amtrak Acela train can be seen. Amtrak doesn't operate outside the United States.

Continuity: Near the end of the movie Bourne goes to 415, East 71st Street in Manhattan. We see him outside of the building which is a modern skyscraper. Once inside he has a conversation with the man that "recruited" him in a white room. When the men that are after him break into the room, he jumps through an older type window onto a rooftop. The window is completely out of place for the type of building he is in. When he falls off the rooftop and into the East River, his fall is only forty to sixty feet, contrary to falling from a roof of a modern skyscraper in downtown Manhattan. In addition the address of the building is several blocks away from the East river.

Continuity: In the scene where Desh is chasing Nikki and Bourne is chasing Desh. There is a shot of Bourne from overhead, you see that he is wearing black converse type tennis shoes (black with white rubber on the toes). As the chase continues, Bourne's shoes are shown several times to be solid black.

Factual error: Bourne hot-wiring the Audi A4 in the car park is pure fantasy. Firstly, it has a transponder around the ignition barrel that picks up the signal from the key: no key, no start, and no amount of splicing of wires will circumvent it, either. Also, at no point does Bourne break the physical steering lock. He shouldn't be able to steer.

Factual error: When Jason is at the internet cafe googling the financial company, the address that comes up for Sydney is not technically possible. The street name (Market Street) is real, but the street number was 18017 which is not possible as the street is only a few blocks long and ends at about 400.

Continuity: In the chase scene involving Bourne and Desh, when Bourne comes to a stop on the rooftop, his jacket is zipped. In the next shot his jacket is open. In the next shot his jacket is zipped, as he begins to run again.

Other: At the beginning of the New York chase sequence where Bourne is walking down the street, you can see an Asian man smiling right into the camera for a second.

Continuity: When Noah Vosen face goes from completely clean shaven (very smooth and shining skin) to very short stubble and back again when is explaning about the secret project to Pamela Landy in his office.

Continuity: When Nicky is first seen in the movie, with Bourne pointing a gun at her, her hair changes between shots.

Continuity: When Pamela Landy is looking at Jason Bourne's induction paperwork, the date of his induction is 06-02-1999. However, the date of his first assassination (Neski) is 1998. The assassination of Kyriacou is also listed as having taken place in 1998. Both dates are obviously before he had completed the Treadstone induction.

Continuity: When Landy is looking at Jason's file it says his blood type is A-. When Jason looks at his old dog tags it says his blood type is O-.

Continuity: The conversation Bourne has with Landy at the end of The Bourne Supremacy is repeated in this film, about an hour and fifteen minutes in - the conversation is absolutely word-for-word identical, so clearly it's the same one. However, in Supremacy, it is a bright, sunny day, but in Ultimatum, the weather is overcast with snow on the ground. Landy's phone rings in Supremacy, but vibrates in Ultimatum. Finally, the other agent doesn't enter her office during the phone call in Supremacy.

Factual error: In the scene where Bourne is traveling to London on the Eurostar from Paris, immediately after the 'flashback' where Marie floats away after being killed, there are two helicopter shots of the Eurostar traveling to London. The second (far away) shot shows the train passing over a motorway. The train is actually traveling towards Paris, and therefore away from London. The motorway is the M20 and the bridge is approximately 3 miles west of junction 9 for Ashford (Kent). The train would have been 10 minutes away from entering the Channel Tunnel.

Continuity: At the end of the movie, in the flashback when Bourne recalls his training process several years ago, Hirsch looks younger, but Bourne looks just like the present date, with an edgy and thin face, opposite to the round-childish face that he had then (which we are reminded of during all the movie via photos in his portfolio).
