Continuity mistake: When Bourne is being chased by the assassin, he leans his seat back all the way in order to switch seats with Marie. After they switch, in the next shot of Marie the seat is back up and she has a seatbelt on. There was no time to do either of those, much less both. (00:15:00)BillyBlake
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?
Continuity mistake: When Bourne does in Berlin the online research in the newspapers about the two murders he is accused of, in the first shot (over Bourne's shoulder) the first word in the entry mask of the search engine is "Medienprodukt" (which, by the way, is a verbatim but bad translation of "media product" and no German would say that). Also in the field "Jahr" (= "year"), we can see that the numbers "198" (instead of 199) have been entered. In the next shot, the close-up of the entry mask, "Medienprodukt" has switched to the better translation, "Medium". The entry in the year field has switched to "1997 - 1999". (00:57:35)
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
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)
Continuity mistake: At the start, the first wire put into the right most portion of explosives changes position between shots.
