The chilling, apocalyptic thriller "28 Days Later" (2002) had virus-infected citizens terrorizing London. In this killer sequel, the virus has been eradicated—or so it was thought. Now the infected have returned, more deadly than ever. Robert Carlyle and Catherine McCormack star as parents trying to keep their two children out of harm's way. Directed by Juan Carlos Fresnadillo, who co-wrote the script with Jesús Olmo, Rowan Joffe and E.L. Lavigne.
