Reports from a February test screening in Soho, London organized by the distributors indicate that the film looks like it is shot almost entirely with a handheld mini DV, enabling "fly on the wall" camera angles and digital distortion effects that give it a feel of gritty reality. It tells an extremely violent and disturbing story from a local viewpoint, with the survivors having no idea how far the virus has spread, creating additional tension. In the opening scene, a disoriented bicycle courier wakes up one morning in a deserted London hospital. While wandering around desolate central London, he comes under attack by zombies, who chase him in a rage trying to infect him with the disease. After being rescued by other survivors, they begin a journey to salvage a future existence from a world gone mad. Director Danny Boyle sat in on the question and feedback session, which included audience opinions that were boisterous and sometimes negative, although overall the film was well received. Of course, commercial success remains a question mark.
