Continuity mistake: When Ethan and the girl are sliding down the rope at the opera, in one shot, as it should be, her dress is up around her neck - that is all we see - and in another shot, the dress is down around her ankles, which it shouldn't be.
Suggested correction: The top of her dress is also fluttery and could have created the illusion that her dress is up around her neck.
That's not the top of her dress we see. The top is fitted over just one shoulder, there's not enough material to cover up her shoulders and neck like it does. It's the bottom of her dress.
Factual error: During the car/bike chase the air bags for the car should have gone off many times, most notably when the car hits the truck with the bike rider on the bonnet.
Suggested correction: The collision mentioned above was an impact at the C-pillar of the BMW. As someone involved in several traffic accidents, I know airbags are not infallible. The only airbag that MAY have been activated would be the side curtain airbag and only if the impact was near the sensor. Normally, side curtain airbags activate only in rollovers or direct T-bones.
