Continuity mistake: In the final scene Regan hails a taxi as it pulls in the taxi is passed by a green Jaguar and a yellow Ford Transit.When the angle changes, these two vehicles should pass by, but they don't.Then when the taxi turns round and drives off, the vehicles in front of it should have been seen in the previous angle but they weren't.
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: When the camera is looking out the window of the flat being used for surveillance, Lennie and Tolman drive past the parked Sweeney silver Ford Granada, a red Peugeot, a blue Peugeot estate, an empty space, then a white Hillman Superminx. The camera then changes to inside the car - Lennie and Tolman pass the Granada and the two Peugeots a second time but there is a brown Ford Cortina parked where the white Hillman Superminx was. Lennie and Tolman drive round the block and drive past a second time, you see the brown Cortina, but when Lennie parks the car in the empty space next to the blue Peugeot estate, the white superminx is back where the brown Ford Cortina was.
