The film Pride and Prejudice is inspired by the play and not the book

Pride and Prejudice (1940 film) is a cinematic adaptation that draws its sources from a successful play. This three-act romantic comedy was written by the Australian Helen Jerome and premiered in the United States at the end of 1935. This choice explains numerous divergences from the original 1813 novel, such as the final transformation of the character of Lady Catherine de Bourgh.
