Even though Stephen King's latest novel 11/22/63 was only released last November, things are already heating up with the planned big-screen version.

In fact, The Silence of the Lambs director Jonathan Demme was attached to write and direct before the novel was even released, and now he's revealed some more details for eager fans.

The book follows a teacher who travels back in time and attempts to prevent the assassination of JFK but, unsurprisingly, things don't go quite as planned. Demme revealed to the Playlist that he's currently working on the script with King himself.

"After all these years, what I’ve come to understand is: don’t plan the script that you’re really thrilled with," he shared. "At the heart of 11/22/63 is this profound, magnificent challenge that our hero is faced with, which is that the past doesn’t want to be changed. Our boy Jake has his work cut out for him if he really wants to change history. He really has to go up against it. And he may or may not succeed."

Demme was rather tight-lipped on whether the movie will retain the same structure as the book.

"You never know. There’s a dozen movies in 11/22/63. We’re finding the one that we think is kind of the best of all. And Stephen is wide open. The book is the book. The movie will be something different. It’s great fun working with him."

Filming is scheduled to begin before the end of the year. Who would you like to see in the lead role?
