Revealing mistake: When the police car crashes through the grating that was dropped down in front of it at the end of the tunnel, the occupants are dummies - they just bounce about in the same upright position whilst the car drives into the river.
Factual error: While Bridger is watching the film of the Mafia boss following Beckerman he signals for the film to be stopped so he can look at the close up shot of the man. He is watching a 16mm film shown through a bog standard projector - stop a film like that for more than two seconds without closing down the projector shutter (this doesn't happen - if it did the screen would darken instantly) and it will melt and catch fire. This doesn't happen.
Continuity mistake: After the gang is pulled off the bank job, they race away in the three Minis - as they go through a tunnel at one point they roll up and down the sides of the tunnel. The mistake is that each car supposedly has two occupants, but on one shot of the cars in the tunnel, one car has only a single occupant - visible because the car following has his headlights on illuminating the car in front.
Continuity mistake: When the 3 Minis are pushed off the coach, if you look carefully there is view shown briefly of the cars interior, which has red door pillars. When the shot reverts to the external view the cars colour is white.
Revealing mistake: When the three Mini Coopers drive onto the coach, the first Mini doesn't have fitted headlights. It also has a brand new rear wheel fitted that is clean and the rest are dirty.
Continuity mistake: When the car transporter is trying to break into the building, where they are transferring the gold from the security vehicle, a car drops from the transporter, lands on a police car, and the blue cover from the police light comes off completely in the first shot. But a second later you see the face of the policeman with the light in the foreground, which now has a jagged broken base left on the car.
Visible crew/equipment: As the armoured truck is midway from the airport to the Fiat plant, the film crew is seen in the mirrored finish of the stripe running down the length of the truck.
Continuity mistake: Each of the Mini Coopers were fitted with three spot lamps on the front grille/bonnet in a triangle formation. In part of the chase sequence through the sewer, two of the Minis have sprouted three more lights - one under each headlamp and one in the centre of the grille under the three original spot lights.
Continuity mistake: Right at the beginning, the red Lamborghini goes into the tunnel and is blown up, yet when it is taken out not one part of the bodywork is charred, it is still a shiny red.
