The battle of good versus evil is going to be violent and lengthy.

In an interview with Vulture, The Fault in Our Stars‘ Josh Boone reveals that his adaptation of Stephen King’s “The Stand” will be 3-hours long and R-rated.

We’re gonna do one three-hour, R-rated version with an amazing A-list cast across the board. Every single one of those characters will be somebody you recognize and somebody you relate to. And it’s gonna be awesome. I’m really excited. It’s the most exciting thing I’ve ever got to do in my entire life. If 12-year-old me had ever known that one day I’d be doing this, to even just go back and look at that kid, I’d be like, Keep doing what you’re doing! It’s just crazy. I’ve met so many actors over the years, and like, when I met Stephen King, I hugged him with tears in my eyes. He meant that much to me when I was young. I still say everything I learned about writing I learned from Stephen King. I don’t read screenplays. I don’t read screenplay how-to books. It’s always just, establish the character. Establish the character.

Nat Wolff recently signed on to star in a story of good versus evil after a virus wipes out most of the American population. It features dozens of characters (including such memorable ones as the Trashcan Man and Mother Abigail) and overlapping storylines running over many years as it tells of a group of survivors fighting the Antichrist-like Randall Flagg.
