Revealing mistake: During the final chase scene with the BMW and the Peugeot. Just as they go down into the first tunnel, they cut in front of a car transporter forcing it to brake hard. A car on top of it then flips forward onto the road. If you look at the ramp as the car tips up, you can see a mechanical arm/rod lift it up to make it fall off.
Revealing mistake: In the final chase a car gets spun around and hit by a lorry - the car driver is an obvious dummy.
Revealing mistake: Obvious studio shot when the BMW starts to flip at the end.
