The Royal Family tells the uproarious story of the Cavendishes, an old and celebrated “First Family” of the theatre. It is a warmhearted and knowing portrait that lives and breathes in the grand tradition of the stage: from Fanny Cavendish, the former leading actress and Grand Dame of a family cheerfully obsessed by the theatre and a beacon of sanity amidst battling, raucous relatives and friends; to her riotous son, Anthony, who is a Hollywood scandal; her daughter, Julia, the stately current leading lady of the Cavendish family; and Herbert, Fanny’s aging brother and former leading man; down to her great-grandson, Aubrey, who, at the age of two months, is already being groomed for the role of Hamlet by his brood of cooing relatives.
