Sir Alec Guinness was an English actor. After an early career on the stage, Guinness was featured in several of the Ealing comedies, including Kind Hearts and Coronets (1949), in which he played eight different characters; The Lavender Hill Mob (1951), for which he received his first Academy Award nomination; and The Ladykillers (1955). He collaborated six times with director David Lean: 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 for Best Actor 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, he played Jacob Marley's ghost in Ronald Neame's Scrooge. He also portrayed Obi-Wan Kenobi in George Lucas's original Star Wars trilogy; for the original 1977 film, he was nominated for Best Supporting Actor at the 50th Academy Awards.

The Ealing comedies is an informal name for a series of comedy films produced by the London-based Ealing Studios during a ten-year period from 1947 to 1957. Often considered to reflect Britain's post-war spirit, the most celebrated films in the sequence include Kind Hearts and Coronets (1949), Whisky Galore! (1949), The Lavender Hill Mob (1951), The Man in the White Suit (1951) and The Ladykillers (1955). Hue and Cry (1947) is generally considered to be the earliest of the cycle, and Barnacle Bill (1957) the last, although some sources list Davy (1958) as the final Ealing comedy. Many of the Ealing comedies are ranked among the greatest British films, and they also received international acclaim.
