The Wrong Arm of the Law

The Wrong Arm of the Law is a 1963 British comedy film directed by Cliff Owen and starring Peter Sellers, Bernard Cribbins, Lionel Jeffries, John Le Mesurier, Bill Kerr and Nanette Newman. The final screenplay was written by John Antrobus, Ray Galton, and Alan Simpson – from an original draft script by John Warren and Len Heath, based on a story by Ivor Jay and William Whistance Smith – and made by Romulus Films. It reunited Sellers, Jeffries, and Cribbins who appeared together in the 1960 film comedy Two-Way Stretch – also written by John Warren and Len Heath – where similarly Sellers and Cribbins played crooks (incarcerated) against Jeffries as an officer of the law, in that case as their chief prison officer.
