The Wrong Arm of the Law is a 1963 British comedy directed by Cliff Owen and starring Peter Sellers, Bernard Cribbins, Lionel Jeffries, John Le Mesurier and Bill Kerr. In London, a gang of criminals from Australia led by Jack Coombes (Bill Kerr) impersonate policemen to carry out robberies. Local gang leader "Pearly" Gates (Sellers), who operates from the cover of a French couturier, finds his takings cut severely, and blames rival crook "Nervous" O'Toole (Bernard Cribbins). When it emerges they are both being scammed by the same gang, they join forces, along with Lionel Jeffries' Police Inspector "Nosey" Parker, to bring the so-called "I.P.O. mob" (I.P.O. - Impersonating a Police Officer) to justice.
