Continuity mistake: During the car chase in Paris, the sun shines when the camera films the front of the car Bourne is driving, but it's grey and gloomy when the camera films the rear of the car. Changes back and forth throughout the entire car chase.
Continuity mistake: In the car chase scene, the windscreen wipers on the Mini change from being on, then to off, then back on again throughout the whole chase. (00:52:42)
Factual error: In the farmhouse scene where Jason is pursuing the other assassin, you can distinctly hear the calls of an American Crow and a Blue Jay, two species of birds that are not found anywhere in Europe.
Revealing mistake: In the night scene where the Professor is driving in the rain to assassinate Womboosi, 2 people are visible in the car when it is shown from the front. Later he states that he always works alone so there is no reason for the other person.
Continuity mistake: After Bourne dyes and cuts Marie's hair, she is left with long tendrils at her temples. He brushes them away when they start kissing. But the next morning, when Marie wakes up in bed, all of the front of her hair is cut short.
Continuity mistake: When Wombosi gets assassinated, the shot changes to a view of the sniper's scope. The glass on the window is not broken, even after a bullet was fired through it. (01:03:44)
Factual error: When Conklin flies to Paris, we see him board a Dassault Falcon 900 that bears the registration "N-GIDE." This is not a valid United States aircraft registration. All US registrations have an "N" followed by up to four alphanumeric characters without a hyphen in between (e. G, N601AW). (01:35:10)
Continuity mistake: In the scene where Jason Bourne first wrestles with the boat's doctor/captain, the man shows Jason the cylinder that was in his hip and asks him why it was there. Jason grabs it and his hands are clean, then in the next shot as the medic is still holding him there is blood all over Jason's hand as Jason continues examining this cylinder, then the blood disappears again.
Continuity mistake: In Bourne's Paris apartment, Bourne takes off his orange jumper and leaves it on the desk. When he kicks Castel over the desk, the orange jumper is knocked to the floor. After Castel goes out the window, the jumper is back on the desk again.
Factual error: 104 Rue du Jardin does not exist in Paris. They stop on a rather large street which would be called a "boulevard" in Paris. Not a "rue." (00:37:05)
Factual error: On the way from Zurich to Paris there's an Aral gas station. There are no Aral gas stations in Switzerland or France, only in Germany and Luxembourg. (00:34:00)
Character mistake: The man in the morgue says in Yoruba "'I told you so, your head is not correct," not what they interpreted.
