Which author has the most book-to-movie adaptations?
Literary adaptations have been a prime source of inspiration for film and television since the very inception of the moving image, a sentiment that rings as true today as it ever has.
Whether it’s prestigious dramas, riotous comedies, globetrotting thrillers, star-crossed romances, or anything in between, the page-to-screen production mine has always been one of Hollywood’s most popular veins to tap. However, some authors have proven a great deal more popular than others.
There aren’t even all that many to have made it into double figures, with the unstoppable rise of Nicholas Sparks proving to be the most recent example. His first novel – The Notebook – was only published in 1996, but there were 11 movies made based on his bibliography between 1999’s Message in a Bottle and 2016’s The Choice.
John le Carré’s assorted spy novels spawned ten films from 1965’s The Spy Who Came in from the Cold to 2016’s Our Kind of Traitor, matching the volume of John Grisham adaptations to arrive between 1993’s The Firm and 2004’s Christmas with the Kranks, while 2017’s The Child in Time was the 11th entry in Ian McEwan’s back catalogue to be given the live-action treatment.
J.K. Rowling finds herself in a similar boat, but it’s all due to the Wizarding World. The Harry Potter saga spawned eight blockbusters and a trio of spinoffs, while even her subsequent Cormoran Strike series has was brought to the screen as the BBC’s Strike. She’s admittedly following in the footsteps of Ian Fleming, who saw 14 of his James Bond novels and short story collections taking on new life on the silver screen, with Chitty-Chitty-Bang-Bang the sole exception.
As the best-selling author in history who’s sold more than two billion copies, it’s unsurprising that Agatha Christie is streets ahead of almost any other competitor. She did have quite the head-start considering the first – The Passing of Mr. Quinn – was released in 1928, with Kenneth Branagh’s recent sequel A Haunting in Venice bringing her up to an even 50.
Sparks, Rowling, Fleming, and even Christie pale in comparison to Stephen King, but only just in the latter’s case. Rob Savage’s The Boogeyman marked the 51st time one of the terror titan’s various books, short stories or novellas had been released either in cinemas, on television, or streaming, and that doesn’t even include the dozens of episodic shows, either.
The most adapted author in history will never be matched…
However, no matter how many times Christie and King continue to be adapted – or any other author who comes along in the future to win over industry creatives – the single most adapted author in history has a record that “unassailable” doesn’t even begin to cover.
His writings and the internet may have been separated by centuries, but IMDb nonetheless credits William Shakespeare as having almost 1800 writing credits, with an additional 42 in various stages of development. Over a thousand of them have been classified as features, too, with a filmed version of King John from 1899, the earliest known example.
