Alec Guinness
Guinness began his stage career in 1934. Two years later, at the age of 22, he played the role of Osric in ''Hamlet'' in the West End and joined the Old Vic. He continued to play Shakespearean roles throughout his career. He served in the Royal Naval Reserve during the Second World War and commanded a landing craft during the invasion of Sicily and Elba. Along with Laurence Olivier, John Gielgud and Ralph Richardson, he was one of the great British theatre actors who made the transition to films after the war, making his name in six Ealing comedies, starting in 1949 with both ''A Run for Your Money'' and ''Kind Hearts and Coronets'' (in which he played eight different characters). He went on to lead roles in 1951 with ''The Man in the White Suit'' and ''The Lavender Hill Mob'' (for which he received his first Academy Award nomination for Best Actor), then in 1955 with ''The Ladykillers'', and culminating in 1957 with ''Barnacle Bill''.
Guinness collaborated six times with director David Lean: as Herbert Pocket in ''Great Expectations'' (1946); Fagin in ''Oliver Twist'' (1948); Col. Nicholson in ''The Bridge on the River Kwai'' (1957), for which he won both the Academy Award and the BAFTA Award for Best Actor; Prince Faisal in ''Lawrence of Arabia'' (1962); General Yevgraf Zhivago in ''Doctor Zhivago'' (1965); and Professor Godbole in ''A Passage to India'' (1984). In 1970, Guinness played Jacob Marley's ghost in Ronald Neame's ''Scrooge''. He also portrayed Obi-Wan Kenobi in George Lucas's original ''Star Wars'' trilogy, which brought him further recognition; for his performance in the original 1977 film, he was nominated as Best Supporting Actor for the Academy Award and Golden Globe. Guinness's later life was closely associated with his definitive depiction of the leading role of George Smiley in the BBC television series ''Tinker, Tailor, Soldier, Spy'' and ''Smiley's People'' by John le Carré.
