And as usual, it sounds like an amazing movie. Per Variety:
Martin Scorsese and Leonardo DiCaprio will reteam early next year on "Shutter Island," a Laeta Kalogridis-scripted adaptation of the Dennis Lehane novel...Drama is set in 1954, with DiCaprio in final talks to play U.S. Marshal Teddy Daniels, who is investigating the disappearance of a murderess who escaped from a hospital for the criminally insane and is presumed to be hiding on the remote Shutter Island. Scouting will begin shortly on the film, which most likely will shoot in Massachusetts, Connecticut or Nova Scotia. Lehane's novel "Mystic River" was turned into a film by Clint Eastwood, and his "Gone Baby Gone" is the basis for the Ben Affleck-directed drama that opened this past weekend. "Shutter Island" was originally optioned in 2003 by Columbia. The option lapsed and Lehane's Gersh reps resold it to Phoenix Pictures. The producer enlisted Kalogridis, the "Alexander" scribe who also wrote "Battle Angel" and "The Dive" for James Cameron. Phoenix and Kalogridis developed "Shutter Island" for about a year.
Scorsese and DiCaprio, who've now worked together on three films, were looking at several projects to do early next year, including an adaptation of "The Wolf of Wall Street." The "Shutter Island" script quickly drew both director and star, and a deal is expected to fall into place quickly.
