Director Danny Boyle and the original cast have all bailed out, but this sequel to the apocalyptic splatter flick 28 Days Later (2002) is still well equipped to rip your face off. By now the highly contagious “rage virus” has swept the entire British mainland, its psychotic victims have all died of starvation, and a U.S.-led multinational force has established a sort of Green Zone whose shell-shocked residents are supposed to repopulate the island. But after the quarantined population is infected, snipers are ordered to shoot the healthy and the crazed alike. Juan Carlos Fresnadillo directed; with Rose Byrne, Robert Carlyle, Jeremy Renner, and Catherine McCormack. R, 99 min.
