In the scene where Regan and Carter are following Don Edwards to the derelict flat where Davey Holmes is hiding, they pass a row of parked cars, with a shop called Chelsea Typewriters in the background. In the shots of Don's bike and the Sweeney's white Ford Cortina, the parked cars are a white Datsun, a red Fiat, a motorbike covered in a blue tarpaulin and a grey Jaguar. In the shot from inside the Cortina, a white Riley is now parked between the Datsun and the Fiat where there was previously an empty space.
During the heated scene where Geraldine Moffat meets Karl Howman in the forest she calls his character "Rick" (her husband's name) instead of Davey.
