28 Days Later is a 2002 British post-apocalyptic science fiction film directed by Danny Boyle. With a screenplay written by Alex Garland, the film stars Cillian Murphy, Naomie Harris, Noah Huntley, Brendan Gleeson and Christopher Eccleston. Set in Great Britain, just after the turn of the 21st century, the story depicts the breakdown of society following the accidental release of a highly contagious virus and focuses upon the struggle of four survivors to cope with the ruination of the life they once knew.
A critical and commercial success, the film is widely recognised for images of a deserted London, and was shot almost entirely on digital video. The film spawned the 2007 sequel, 28 Weeks Later, as well as the graphic novel 28 Days Later: The Aftermath.
