Directed by Cliff Owen and scripted by the incomparable British comedy writers Ray Galton and Alan Simpson (Hancock’s Half Hour, Steptoe and Son) with John Antrobus, The Wrong Arm of the Law brings together a Who’s Who of familiar faces from British film and television of the 60s and 70s, not least the legendary Peter Sellars (I’m Alright Jack, The Ladykillers).

In London, a group of Australian gangsters disguised as “Bobbies”, led by Jack Coombes (Bill Kerr, The Dam Busters), are diverting the ill-gotten gains of the local criminal gangs. Gang leader “Pearly” Gates (Sellers), who operates from the cover of a French couturier, finds his takings severely cut. Initially he blames rival crook “Nervous” O’Toole (Bernard Cribbins, The Railway Children) but when it emerges that they are both being scammed by the same gang, they form an unlikely alliance with Scotland Yard Police Inspector “Nosey” Parker (Lionel Jeffries, Nowhere to Go) – to eliminate the so-called “I.P.O. mob” (I.P.O. – Impersonating a Police Officer) and return things to “normal”.
