Kind Hearts and Coronets is a 1949 British crime black comedy film directed by Robert Hamer. It features Dennis Price, Joan Greenwood, Valerie Hobson and Alec Guinness; Guinness plays eight characters. The plot is loosely based on the novel Israel Rank: The Autobiography of a Criminal (1907) by Roy Horniman. It concerns Louis D'Ascoyne Mazzini, the son of a woman disowned by her aristocratic family for marrying out of her social class. After her death, a vengeful Louis decides to take the family's dukedom by murdering the eight people ahead of him in the line of succession to the title.

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.
