Visible crew/equipment: When Dewey is introduced and has a phone call with Jeffers about the leak, he is packing away files in a briefcase. On his desk there is a pad of paper beneath Dewey's mobile, and the scripted lines for Dewey's side of the phone conversation are handwritten on the top sheet, not being removed from set prior to filming.

Factual error: When Bourne first arrives in London, the Audi he is driving is quite obviously left hand drive. In the UK his car would be a right hand drive.
Factual error: In the car chase, the SWAT truck throws cars in a traffic jam upwards and to left and right, as if it had a large, pointed snowplough type structure mounted to its front bumper. The front of the truck is squared off and blunt - it would just shorten the car in front - as some of us know from tail-ending experience.
Other mistake: In one of the car chase scenes, Bourne has to turn left down a street because the police have blocked the road ahead. Soon afterwards, he has to turn left down another street because the police have blocked it off too. The same footage is used again.
Factual error: When Bourne goes to Berlin, he supposedly heads for Kollwitzplatz. There is even a street sign in the shot to reinforce that connection. Problem is that Kollwitzplatz is in Prenzlauer Berg and Bourse is actually heading down Falckensteinstrasse. You can see the Oberbaumbrücke in the background. Presumably, Kollwitzplatz, as a famous iconic location seemed like a better choice. If you compare it to google street view, you can see how they changed the traffic signs. (00:43:47)
