Revealing: After Jason is dropped off on land, he is seen walking away from the camera, then disappears as a vehicle passes him. If you look carefully at the vehicle after it's passed him, it's possible to see feet and a shadow belonging to someone running behind it.

Continuity: In the farmhouse scene Bourne looks out a window and it is bright outside. When he looks out the glass in the door and it is dark outside. When Bourne goes outside it is bright again.

Continuity: In the scene where Jason and Marie go to Jason's residence in Paris, Jason picks up a Bic Pen to write while he's talking on the phone to the hotel. He takes the cap off and places it on the back of the pen. In the next shot, the cap is missing from the back of the pen.

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.

Continuity: Just before the car chase, a police car pulls up behind their mini, but when they race off it's no longer there.

Continuity: When Wombosi is shot, the bullets come through the bottom of the window which has bars. From the outside, we are shown that the shots go into the top of the window, and there are no bars on it.

Continuity: When Jason enters the train station to stash the red bag, the large clock on the outside of the station reads exactly 12 noon. Once he's inside the station the clock reads after two.

Factual error: When Matt Damon enters the station, the clock reads 12noon. 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 5 hours of departures. It is usually only about 1hour at that time of the day.

Revealing: There is no snow at all on any surface higher than the second floor of the consulate, except for the sill Bourne is climbing on, and the fire escape.

Continuity: The handgun has black slide on it and shortly later, the same handgun has nickel slide on it.

Continuity: At the beginning of the car chase, the red car has a burnt out leftside tail light. For the remainder of the chase, it's working.

Continuity: In the scenes during which Bourne and Marie are driving the Mini Cooper, interior shots are of at least two different cars, neither of which is the older model Mini Cooper featured in external shots. Interiors feature three-point seat belts, far more plastic than one would find on the original Mini, and in at least one shot, a steering wheel that appears to contain an air bag. Minis did not have any of this stuff until the 1990s, while the car used for exterior shots is of 1970s vintage at latest.

Visible crew/equipment: When Eamon is running away with Marie and his kids, the camera passes behind the car and a crew member is reflected in the trunk.

Continuity: In the scene where Bourne is moving up the stairs in the embassy, as he approaches the 5th floor you see the legs and feet of someone either standing, or perhaps an evacuee. In the shot immediately following, the person is gone.

Continuity: In the scene at Treadstone HQ's where Cris Cooper is looking at the screen of the mini that Matt Damon is getting into, he takes off his glasses. It goes to the screen and then goes back to Cris Cooper and he takes off his glasses again and puts them in his breast pocket.

Continuity: When Conklin is going to meet Bourne on the bridge, the people walking behind or to the side of him are constantly changing between shots.

Continuity: When Jason is climbing down the side of the bank, there is a car in the snow. When the camera cuts directly to him, then back to the aerial view, the car is gone, there are no tracks and it isn't snowing hard enough to cover the tracks.

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 shields on the walls are sometimes written in Czech language, and the people speak German with a strange (Czech) accent, not like someone from Zürich.

Continuity: When Chris Cooper is going to meet Bourne on the bridge, he passes an agent in a wool cap who is facing the street. The shot changes to Bourne looking through the scope, and the man in the wool cap has instantly turned 180 degrees to face the water.

Visible crew/equipment: Right at the end of the car chase, the yellow van in the pile-up is flipped over by some kind of large metal lever in the undercarriage. This is seen from the last 2 angles of the crash.
