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.
Continuity mistake: The blue van turns right by a pub with a large car park - when the squad car takes the same turning a few moments later more cars have appeared in the car park.
