When Petra and Yuli run up to fight the three Ninjas, Petra is wearing white panties, not so during the fight.

When arriving at the airport, the taxi switches from normal windows to black tinted windows and back.

The bullet-proof Peugeot has black tinted windows in the aircraft hanger except when the airbags go off - you can see the driver squashed inside the car.

When Petra is kidnapped in the toilet stall, she leaves her panties behind. Later, she is wearing panties during the flight with the ninjas.

During the chase trough the market place, the air-intakes on the top of the taxi disappear and the come back in the next shot. This also happens in the Paris police station scene, or when they board the taxi after the ninja fight in the building in construction.

The Mitsubishi cars used by the bad guys have Japanese license plates and were presumably imported from Japan. However these are the cars with the steering wheel on the left, not on the right, as the imported Japanese car should have.

When all of Paris' police cars are taking part in the chase, it's clear in many shots that every one of them has only one person inside: the driver. This may be very practical for financial and safety reasons for a movie shoot, but not very likely in the real world, where policemen usually move in pairs.

At the very end of the movie, while Lilly and her mother are watching the July 14th parade, the shadow of a crew member can be seen on the wall.

When Daniel stops the truck on top of which he's stuck, the reflection of both the stunt driver and the cameraman can be seen. Also, the stunt driver is clearly not the same person as the driver seen in the previous shot.

When the taxi goes through a Parisian police station, a cameraman, a camera and especially a boom mike are visible in a shot, in the middle of the screen, right before the drifting taxi hides them.

During the Parisian chase, a police car collides with an orange Ford van. In all of the shots around this scene, a film camera is clearly visible on the passenger side seat of the van which was used to record the shot shown just before the collision.

Like in the first movie, Émilien rams the driving school car into a shop. But in France, these cars are equipped with pedals on the passenger's side so that the driving instructor can avoid these situations.

There's no way the Yakuzas downstairs didn't hear a thing during Petra & Yuli's brawl against the ninjas in the building.
