28 Weeks Later is a 2007 British post-apocalyptic horror film directed by Juan Carlos Fresnadillo, the sequel to Danny Boyle's 28 Days Later. Set six months after the original Rage virus devastated Britain, the film follows the U.S.-led NATO force's attempt to repopulate London, starting with a secured zone on the Isle of Dogs. When a carrier of the virus — someone infected but asymptomatic — enters the safe zone and triggers a new outbreak, the military's containment protocols escalate from quarantine to extermination of all civilians, infected or not.

Robert Carlyle starred as Don Harris, a man whose cowardice during the initial outbreak has devastating consequences when his infected wife reappears. The opening sequence, depicting Don's panicked abandonment of his wife during a Rage attack on their rural sanctuary, was one of the most intense and morally harrowing openings in modern horror. The helicopter-through-a-field-of-infected sequence became the franchise's most spectacular action set piece. 28 Weeks Later earned $64 million worldwide on a $15 million budget.
