Hulu made the announcement today, making this Hulu and WBTV’s very first original programming collaboration. Abrams, King, Carpenter and Bryan Burk will all executive produce. Here’s what Abrams had to say about the project:

“I’ve been a fan of Stephen King since I was in junior high school. The chance to work with him at all, let alone on a story so compelling, emotional and imaginative, is a dream. We are thrilled to be working with Hulu on this very special project.”

And here’s what King added:

“If I ever wrote a book that cries out for long-form, event TV programming, 11/22/63 is it. I’m excited that it’s going to happen, and am looking forward to working with J.J. Abrams and the whole Bad Robot team.”
