Continuity: The bullet deflector on the red Lotus is down and then up again on the following shot.
Revealing mistakes: As Michael climbs down the side of the house in the last scene (carrying Mariska), an explosion occurs and you see his feet lift off the side of the wall. His shoes are supposed to have suction that hold him up, if his shoes lift he should fall - but he does not move.
Continuity: At the dinner table, the champagne glass in front of Michael is alternately full and empty.
Factual errors: Both the Lotus Esprit and the Nissan 300ZX are US models, shown by the different lights, different body styles (that model of 300ZX was never sold in Europe, and has a French number plate over the smaller US plate mounting), and that year of Esprit was never sold with an air bag in Europe.
Revealing mistakes: As Michael runs through the hotel room after the rocket is fired into it he doesn't have any socks on. When he emerges through the door he is putting on his trainers on over his socks.
Revealing mistakes: In the hotel room while Korben is trying to figure out the condoms, a missile is fired at his bed. Even before the missile hits the bed the room looks destroyed.
