Overview

28 Days Later is a British horror film released in 2002 that redefined the zombie genre by introducing a fast-moving, rage-filled infected population. Directed by Danny Boyle and written by Alex Garland, the film blends psychological tension with apocalyptic dread, centering on a man who awakens from a coma to discover a collapsed society.

The film was notable for its low-budget production techniques and use of real locations, including an eerily empty London filmed at dawn. It launched a new wave of post-apocalyptic storytelling and influenced numerous films and TV series, including The Walking Dead.

Release date: June 27, 2002, in the United Kingdom, with a U.S. release following in November 2002.
Budget: The film was made on a modest $8 million budget, primarily funded by Channel 4 and the UK Film Council.
Box office: It earned $45.6 million in North America and $37.1 million internationally, totaling $82.7 million worldwide.
Technology: Shot entirely on 24p digital video using Sony PD150 cameras, a rarity for theatrical films at the time.
Setting: Principal photography took place in real London locations, including Westminster Bridge, which was filmed at 5 a.m. to avoid crowds.

Plot & Production

The film follows Jim, a bicycle courier who wakes up 28 days after a viral outbreak has decimated the UK population. He teams up with other survivors to escape military quarantine and navigate the dangers of the infected and authoritarian forces.

Origin of outbreak: Animal rights activists break into a lab in Cambridge, releasing a virus called "rage" that spreads through blood and saliva.
Transmission: The rage virus spreads rapidly via bodily fluids, causing victims to become violent within seconds of exposure.
Cast: Cillian Murphy stars as Jim, with Naomie Harris as Selena and Brendan Gleeson as Frank.
Director: Danny Boyle, known for Trainspotting and Slumdog Millionaire, brought a gritty realism to the film’s visuals.
Music: The haunting score by John Murphy includes the iconic piece "In the House – In a Heartbeat," later used in Watchmen and Guardians of the Galaxy Vol. 2.
Runtime: The film runs for 113 minutes and was edited to maintain a relentless pace, enhancing its tension.
