Hilary and Jackie is a 1998 British biographical film directed by Anand Tucker. The screenplay by Frank Cottrell Boyce is often claimed to have been based on the memoir A Genius in the Family (later republished under the title 'Hilary and Jackie') by Piers and Hilary du Pré, which chronicles the life and career of their late sister, cellist Jacqueline du Pré.
