Jack Warner started acting with the Sutton Amateur Dramatics Club after the end of World War I. From 1935, performed in cabaret at the London West End as half of the double act of Warner & Darnell. In addition to starring as Dixon of Dock Green (1955), which ran for over 20 years, he achieved lasting popularity on screen in the role of Joe Huggett, patriarch of a Cockney family, in Holiday Camp (1947), and its three sequels (plus a radio serial). Towards the end of his working life, 1976-80, Warner made a brief return to cabaret, before a stroke brought about his retirement.
