Kind Hearts and Coronets is a razor-sharp 1949 British black comedy about Louis Mazzini, a disowned heir who calmly plots to climb to a dukedom by removing eight relatives - all memorably played by Alec Guinness. Celebrated for its wit, elegant satire of the aristocracy, and inventive performances, it remains one of Ealing Studios greatest triumphs. Critics praise its clever script, dark humour and timeless appeal.
