Ronin (1998) - 6 major mistakes

Continuity: During the big car chase the Audi S8 rams the Citroen, pushing back the headlights on the Audi but on the subsequent scenes in the town the front of the Audi is intact.

Continuity: During the chase scene, there is a Citroen XM series II (the citroen sign in the middle, on the front) and then there's a Citroen XM series I (the citroen sign on the driver's side, on the front). It changes back and forth a couple of times. There's also a difference at the bottom of the car; the series I carries the name Citroen XM on the left side, while the series II bears a Citroen sign on the left side and the XM sign on the right.

Visible crew/equipment: When Vincent and Sam are running through the ice rink's changing rooms to get the case off Gregor, the camera passes a mirror. If you pay attention, you can quite clearly see the boom operator wearing a blue and white checked shirt in it.

Continuity: At the end of the Paris car chase with the BMW M5 and the Peugeot, actor Jonathan Pryce fires a few shots at De Niro and Jean Reno in the pursuit car. One shot takes the left wing mirror clean off, and De Niro even jerks his head to the side in reaction to the shot. The mirror comes off in mid frame, and you can even see the adjustment wires dangling from the mirror base. In all subsequent scenes, the mirror is back on the car.

Visible crew/equipment: During the initial chase with the Audi S8 immediately after the messed-up arms deal, you can see exhaust fumes and tire smoke from the leading camera car in most front shots of the gang.

Factual error: Supposedly the holders of the mystery briefcase are holed up in Nice; but when De Niro and McElhone go to check out the bad guys security arrangements at their hotel, the hotel is in Cannes (believe me) and the Michelin Green Guide that De Niro is carrying is opened to a map of Cannes.
