My Learned Friend: My Learned Friend is a 1943 British, black-and-white, comedy, farce, directed by Basil Dearden with his regular collaborator, Will Hay, as the film's star in the role of William Fitch.  The principal supporting roles were taken by Claude Hulbert and Mervyn Johns .  Character roles went to Laurence Hanray as Sir Norman, Charles Victor as "Safety" Wilson, Ernest Thesiger as Ferris and Ronald Shiner as the Man in Wilson's café.  It was produced by Michael Balcon, Robert Hamer and Ealing Studios.  The film's title refers to a tradition in British law: when addressing either the court or the judge, a barrister refers to the opposing counsel using the respectful term, "my learned friend".  It was the last film featuring Will Hay as he had an operation, however, it wasn't the last role in his career as he would star as "Doctor Muffin" in The Will Hay Programme that aired on the radio, the radio show began in 1944.  The humour of the film was different from the humour of Hay's films he previously made with Moore Marriott and Graham Moffatt and the film had more of a dark humour than any of Hay's other films.  Hay had planned to make more films with Claude Hulbert that had a dark humour, but it was Hay's last film due to illness.
