Private Schulz

A British comedy in six parts from 1982, written by Jack Pullman and starring Michael Elphick, Ian Richardson and Billie Whitelaw.
The plot is based on the true story of Operation Bernhard, a scheme devised by Himmler's SS to ruin the British financial system by forging tons of five pound notes and dropping them on England.
Ian Richardson is perfect as the incompetent Major Neuheim, but what makes the series special is Jack Pullman's script.
