HBO is reportedly in the early stages of developing "Ashecliffe," a TV series prequel to the 2010 Martin Scorsese feature "Shutter Island".
The story would be set at the isolated mental hospital depicted in the Leonardo DiCaprio film with the events in the series taking place before those in the film and Dennis Lehane's 2003 novel on which the movie was based.
The plan is to explore the hospital's past and the misdeeds by its founders. If it moves forward, Scorsese would direct the pilot while both Tom Bernardo and Lehane would pen the script.
Scorsese, Lehane, Brad Fischer, Leonardo DiCaprio, Jennifer Killoran Davisson, Laeta Kalgridis, Rick Yorn, Chris Donnelly, Emma Tillinger Koskoff, Mike Medavoy and Arnie Messer would serve as executive producers.
