In the scene where Mr de Courcy's Rolls Royce is ambushed, Garret's orange Porsche is seen through the Rolls's rear window as it is about to overtake. At this point the cars are on a dual-carriageway. This is immediately followed by a shot of both cars from a camera car ahead of them, as the Porsche continues to overtake, but they are now on a single-carriageway country lane.
