Reginald McKern, AO (16 March 1920 – 23 July 2002), known professionally as Leo McKern, was an Australian actor who appeared in numerous British, Australian and American television programmes and films, and in more than 200 stage roles. Notable roles he portrayed include Clang in Help! (1965), Thomas Cromwell in A Man for All Seasons (1966), Tom Ryan in Ryan's Daughter (1970), Paddy Button in The Blue Lagoon (1980), Dr. Grogan in The French Lieutenant's Woman (1981), Father Imperius in Ladyhawke (1985) and, in the role that made him a household name as an actor, Horace Rumpole, whom he played in Rumpole of the Bailey. He also portrayed Carl Bugenhagen in the first and second installments of The Omen series. He bears the distinction of playing Number 2 opposite Patrick McGoohan in three episodes of TV's The Prisoner (1967).
Although he sounded very British, Leo McKern was an Australian. By the time he was 15 years old, he had endured an accident that left him without his left eye. A glass eye replaced it - one might conjecture for the better, as far as making McKern a one-day actor of singular focus (no pun intended; his face had that extremely focused look). He failed to complete Sydney Technical High School, though his interest in engineering prompted him to transfer into the role of engineering apprentice (1935 to 1937). He expanded his horizons in a different direction with a two-year stint (1937-1940) at a commercial art college. By then World War II was escalating toward Australia, and he volunteered for service with the Engineering Corp of the Australian Army (1940 to 1942). But yet one more career move was needed, and that while the war moved northward away from Australia when America joined the fight. He studied acting and debuted on stage in 1944. He also met an Australian stage actress (Jane Holland), and mutual attraction took its course. In 1946 she had acting opportunities in England, and McKern decided that, along with the wish to propose to her, his own future as an actor lay there also.
