Factual error: When Bourne arranges the rendezvous on the bridge (Pont Neuf) the time is scheduled for 5:30pm. At this time, in winter, in Paris, it would be dark, but the scene is in daylight. (01:34:05)
Factual error: All the scenes which are supposed to play in Zürich were being shot in Prague, the capital of Czech Republic. The director didn't choose Zürich because the city was too clean for him. The signs on the walls are sometimes written in Czech language, and the people speak German with a strange (Czech) accent, not like someone from Zürich.
Factual error: When Matt Damon enters the station, the clock reads 2:30. On the board inside the station, the timetable shows some trains leaving at 5pm. In this busy train station in Paris, it would be impossible to list 2+ hours of departures. It is usually only about 1 hour at that time of the day.
Factual error: At the Zurich bank scene Jason's Russian passport is shown. The name is Foma Kiniaev as it is written in Latin letters. But the Cyrillic text isn't the same, it actually doesn't mean anything. The transcript is something like "LSTSFUM ASF". The place of birth is written as "Moscou" which is the French spelling of the name of the city. The passport is bilingual, Russian/English, so it'd be MOCKBA/MOSCOW. (00:17:11)
Factual error: After the scene where Bourne is returning to his hotel to find the police surrounding it he smashes a police car window to take a "wanted" poster from the front seat. This poster is titled "Gesucht" which is German. Requests for assistance from another police force would not simply be a matter of faxing a wanted poster to the nearest police station over the border. The request would be given to a national body who would then have translated the request to French before distribution.
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)
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)
Factual error: When Jason asks Marie for the pay phone number in front of the Hotel Regina, she gives him a 7-digit number, 616 2468. A French phone number would be 8 digits, not including the (0)1 prefix. (01:01:35)
Factual error: When Bourne gets off the ship in the very beginning of the film, he is in the harbour of Imperia in Italy. Then he travels to Zurich by train. On the seats of the train you can see the logo TGV which are the French Railway's high speed trains. A French train doesn't travel from Italy to Switzerland.
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: At the start of the final scene where Jason is looking down at the scooter shop you can distinctly hear the calls of a Pacific bottle nose dolphin. This species of dolphin is not found anywhere in the Aegean or Mediterranean sea. Also from where Jason was standing you would not hear that type of call.
