The original film was directed by Danny Boyle and written by Alex Garland, and was a critical and commercial success. Following the film's success, a 2007 sequel, 28 Weeks Later, directed by Juan Carlos Fresnadillo, was made; like the previous film, it also garnered generally positive reaction from critics, and was a box office success. 28 Days Later also spawned a graphic novel called 28 Days Later: The Aftermath, which expanded on the origins of the Rage virus and the timeline of the outbreak; and a 2009-2011 comic book series of the same name, which continued the story of, and expanded on the backstory of, one of the main characters of the first film.
