In the pre-credits scene where the two men are attacked and bundled into the robbers' blue Transit van, the shot from inside the van shows a dark Mercedes parked on the right hand side of the road just after the van goes under the railway bridge. However in the reverse shot of the two men being followed by the van, a blue Ford Zephyr is parked in front of the Mercedes. Also the weather changes: in some shots it is raining whereas in others it is not.
