28 Days Later to stream on Netflix: Here’s when to watch the Cillian Murphy film online

28 Days Later is directed by Danny Boyle and penned by Alex Garland. The post-apocalyptic horror film was produced by Andrew MacDonald, and it was released on June 27, 2003, by Fox Searchlight Pictures. Here's the official synopsis as mentioned on the website Letterboxd:

Twenty-eight days after a killer virus was accidentally unleashed from a British research facility, a small group of London survivors are caught in a desperate struggle to protect themselves from the infected. Carried by animals and humans, the virus turns those it infects into homicidal maniacs – and it’s absolutely impossible to contain.

The film will start streaming on Netflix.

28 Days Later will start streaming on Netflix from Saturday, September 20, 2025. On that same day, 28 Years Later will also drop on the streamer. This will allow audiences to experience both films from the horror franchise on one platform. The first film in the franchise follows a bicycle courier who wakes up from his comatose state and realizes that society has collapsed after a virus outbreak.
