Other mistake: During the hold up when Medhurst is sprung from the police van, the breakdown truck used to pull the doors of the van reverses towards the police van twice after releasing the chains off the doors before driving away, and the camera lights are reflected in the side of the white getaway car.
Continuity mistake: In the yard behind the furniture shop when Regan and Carter are nearly crushed by the reversing van they escape by climbing up some old cabinets and then jumping on the van roof. Regan then jumps down on the bonnet before banging on the windscreen and having a go at the driver. Carter has disappeared when he should be visible on the van roof. Then when the Irish man comes out of the shop Carter has reappeared, climbing down from the roof to the bonnet of the van, also the two stunt doubles have darker hair than John Thaw and Dennis Waterman.
