Which 1949 Ealing comedy features Alec Guinness playing eight members of the D'Ascoyne family?

The 1949 Ealing comedy in which Alec Guinness plays eight members of the D’Ascoyne family is Kind Hearts and Coronets.

Dennis Price stars as Louis Mazzini, a man who seeks revenge against the aristocratic family that rejected his mother. He plots to eliminate the eight relatives ahead of him in the succession to the dukedom, creating the film’s elegantly macabre comic premise.

Guinness plays all eight targeted D’Ascoynes, including a duke, a reverend, a general, an admiral, a banker, a banker’s son, a suffragette and a photographer. Clever framing, costume changes and editing make the multiple performances central to the film’s charm.

Robert Hamer directed the movie for Ealing Studios, adapting Roy Horniman’s 1907 novel Israel Rank. It is often grouped with Passport to Pimlico and Whisky Galore! as one of Ealing’s great postwar comedies, but The Ladykillers is a different Ealing film and does not feature Guinness in eight family roles.
