A feature film adaptation of Stephen King's Cell has been in development for quite some time, but it's expected to begin shooting early next year. John Cusack is already on board to star in the movie and it has just been revealed that Samuel L. Jackson will be joining him.

According to Deadline, "Jackson plays Tom McCourt, an engineer and former soldier who with Cusack’s Clay Riddell character flees from Boston as the world turns mad thanks to the phones." For those who are unfamiliar with the novel, Stephen King's Cell was originally published in 2006 and involves a cell signal that turns most of the population into zombies:

"Artist Clayton Riddell had been in Boston negotiating a successful deal to sell his comic book project.  His joy at finally hitting it big is shattered by an event called The Pulse which causes all those who were using their cell phones at the time of The Pulse to become zombies attacking and killing anyone in their way.  Fortunately for Clay, he does not own a cell phone.  In the panic to get out of Boston and find his way home to his wife and son in Maine, he is joined by Tom McCourt, a man he meets in the meleé immediately following The Pulse and a young girl, Alice, who they rescue from being killed by one of the “crazies.”  The story follows their terrifying journey, avoiding capture—and worse—by the “crazies” who are beginning to “flock” and are led by one they call Raggedy Man as they attempt to reach Maine and a place called Kashwak which they hope will be their salvation. "

Paranormal Activity 2's Tod “Kip” Williams is directing, with Adam Alleca (The Last House On The Left remake) and Stephen King having worked together on the script. *Updated with official press release:
