Two cars were used for filming the chase sequence when Regan and Carter's brown Ford Consul pursues the robbers' grey Jaguar: the real NHK 295M and also a damaged stand-in double. Billy Murray (Brian Cooney) drove the real NHK 295M that is seen in other episodes - sometimes at speeds of up to 70 mph - but for sections of the chase where the Consul is very close behind robber's car and when they bounce over rough ground, a damaged replica was used, driven by a stunt driver. On close inspection, the difference between the cars is evident: the real car has an aerial on the front wing which the stand-in one does not, and the amount of damage to the offside indicator changes from shot to shot.
Peter Brayham, who worked as stunt arranger for The Sweeney, had the original idea for this episode and wrote a draft script on which Allan Prior based the script that was used for the episode.
Billy Murray (Brian Cooney) previously appeared with Dennis Waterman in Up the Junction (1968) and later appeared with him in Second Hand Pose (1984) and Fiddler on the Hoof (1989). He later became best known for playing Don Beech in The Bill (1984) from 1995-2004.
