J.J. Abrams‘ Bad Robot is in negotiations for the rights to Stephen King‘s bestselling 2011 novel 11/22/63. The deal is being done through Warner Bros TV, where Bad Robot is under a deal. I hear the plan is to adapt the book as a TV series or miniseries, likely for cable. 11/22/63 centers on Jake, an unassuming divorced English teacher who stumbles upon a time portal that leads to 9/9/1958 and goes on a quest to try and prevent the assassination of John F. Kennedy, which occurred on November 22, 1963.
On August 12, 2011, well before the novel's release, it was announced that Jonathan Demme has attached himself to write, produce, and direct a film adaptation of 11/22/63 with King serving as executive producer. However, on December 6, 2012, Demme announced that he withdrew from the project, after disputes with King over what to include in the script.
