VIDEO: Cell trailer - your phone is really bad for you

Cell is 2006 novel by Stephen King which is basically about a zombie apocalypse which spreads via mobile phones around the world.

The novel was quickly snapped up for a film adaptation with Hostel's Eli Roth originally attached 10 years ago, then progress became slow and he left a few years later to pursue other projects.

Must later, King himself said he was working on a new version of the script with a different ending and it wasn't until 2012 that John Cusack was finally cast in the lead role, alongside fellow King adaptation alum Samuel L Jackson - they both featured in 1408.
