Continuity mistake: During the chase scene on the bridge involving the tank, two cars (silver Toyota Corolla hatchback, licence NE34 12 and a black VW Bora, licence NU67 67) appear during many shots, often travelling in different directions on the bridge and either ahead or behind the chase.
Continuity mistake: During the scene where the cable is shot into the sides of the cliffs to stop the convoy, there are no civilians in the area. As soon as the convoy hits the cable and stops, you can see two normal cars just feet away from it. Not only were the cars never there before, but they would have also gotten stopped by the cable.

Right before he does this, suddenly a massive gap has appeared between the cars.
Continuity mistake: After the first big action sequence in London, the gang meets back in their HQ to discuss the next course of action.
