Other mistake: In the scene where Jason drops from the bridge to the boat, you see him grab his left leg/knee in pain. But throughout the rest of the film, you see him limping on his right leg.
Factual error: When Bourne arrives in Moscow at Kievskii station, he goes to check the address of the dead Russian reformer's daughter, looking in a phone booth yellow pages. There are no phone books, much less yellow pages, in Moscow phone booths. (01:21:20)
Continuity mistake: When Bourne makes the call to Pamela Landy from the rooftop, we hear him talking about Nicky. When the camera switches to her, we see she is across the room, away from Pamela. In the next shot, with the view from outside the window, she is standing right next to Pamela, and then moves back again in the next shot.Scrappy
Other mistake: When Bourne is looking up the address of Hotel Brecker on the website, the street is spelled Kurtürstendamm. It should read Kurfürstendamm with an F. The English translation of this famous street's name is "causeway of the electoral princes"
Revealing mistake: Early in the movie during the scene which Jason Bourne is being detained, the person from the Consulate while questioning Jason Bourne gets interrupted by a cell phone call. He has a Hand Spring PDA/phone and during the phone conversation you can see a red light flash on top of the phone. If you own one of these phones you know that means you have no cellular signal. How could he be having a phone conversation if he has no signal?
Deliberate mistake: When the Neski file exchange takes place in the beginning, the Russian says "You can see who stole the money" and the camera shows the Russian documents. The documents (written in Russian), are in fact, a "Journal of Military Activity of Russian Army in April 1945." It is completely bogus and have nothing to do with the film. (00:07:15)
Continuity mistake: When being pursued by the Russian agent in India, the girl is shot through the rear window of the vehicle. Yet when the vehicle is pulled out of the river, the rear glass is intact.
Continuity mistake: In the main car chase through Berlin, Jason's car is T-boned by the Russian assassin's black Mercedes 4x4. We see a shot of the car spinning and the back bumper/fender is hanging off, held on only by it's very tip on the left hand end and dragging behind. However, in all subsequent shots it's still attached.
Continuity mistake: The blue Saab convertible belonging to the Berlin-based assassin is parked with all wheels on the road when the call-in team arrives in a silver 4x4. Shortly afterwards, the same car parked almost completely on the sidewalk when the assassin's house explodes. (00:41:50)
Factual error: When Bourne's passport is checked at the border leaving Germany to Moscow, his fake Russian last name, Kiniaev, is incorrectly spelled in Cyrillic (Kiniyaev). (01:18:15)
Continuity mistake: At the start, the first wire put into the right most portion of explosives changes position between shots.
