Factual error: When Bourne is tapping into the phone of the American consulate investigator, the display of his Siemens cell phone shows Pamela Landy's phone number as an incoming call, giving him the option to reply or reject the call. But at this point, they have already been talking for a while.
Continuity mistake: In the chase scene toward the end, both Bourne's and the assassin's vehicles are racing down a tunnel. Both of them run several cars off the road while passing them, which should block traffic behind them. Instead, in one long shot of the tunnel, a ton of moving cars can still be seen directly behind them in the tunnel as if traffic was completely normal. Furthermore, even if there was room to drive around the obstructions, nobody thinks it's a good idea to back off from two cars smashing into things?
Factual error: When Bourne drives from Naples to Berlin, he wakes up from a nightmare at Dreilinden, just outside of Berlin (easily recognizable by the bridge in the background). A few scenes later he is seen driving through an Alpine landscape which he should already have passed long before getting to Germany.
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.
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?
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: At the start, the first wire put into the right most portion of explosives changes position between shots.
Nicky: They know you were there.
Jason Bourne: Stop, stop! A weeek ago, I was 4,000 miles away, in India, watching Marie die. They came for me, and they killed her instead. This ends now.
