Forrest Wickman IMDBs the authors who've had the most success at turning their books into films:
What are the surprises? After Shakespeare (the leader by a mile with 831 titles) comes not Brontë (35) or Philip K. Dick (21), but Anton Chekhov (320). Hemingway (56) gets destroyed by Stephen King (127). Dr. Seuss ties Franz Kafka at 70, Joseph Conrad ties Sophocles at 62, and Homer ties Raymond Chandler at 34. Emily Brontë edges out her sister, Charlotte, by one title.
It seems there's no one way to win Hollywood's favor. Short story writers (Poe, O. Henry) and playwrights (Shakespeare, Molière, Wilde) fare at least as well as novelists (Dickens, Hugo). Prestige doesn't necessarily help, either: Writers of such genre fare as science fiction (HP Lovecraft, HG Wells), mysteries (Conan Doyle, Agatha Christie) and fairy tales (Hans Christian Anderson, the Brothers Grimm) often surpass the literary greats. Finally, sometimes penning just one timeless story is enough to become a perennial Tinseltown favorite: Nearly every one of Cervantes' 101 credits is for an adaption of Don Quixote.
Jennie Yabroff explores the battle between sisters Charlotte or Emily Brontë.
