Based on a book by Stephen King, this spooky thriller requires a massive leap of faith on the part of the audience in order for the premise to work. A brain-scrambling electropulse is sent through the mobile phones of the world, turning everyone who was using them at the time into rampaging zombies. And it just so happens that pretty much everyone, bar a scrappy band of survivors fronted by comic-book artist Clay (John Cusack) and train driver Tom (Samuel L Jackson), was using their phone at that exact moment. The slapdash quality to the plotting is matched by the inept film-making – the dialogue is frequently inaudible, the night scenes murkily lit. And yet there are a few creepily effective moments where the techno-horror connects; a few glimpses of an interesting film that might have been.
