EXCLUSIVE: The new 28 Years Later trilogy from director Danny Boyle and Sony Pictures is gaining momentum, and some serious star power. Sources tell Deadline that Jodie Comer, Aaron Taylor-Johnson and Ralph Fiennes have boarded the first pic, a sequel to the original 28 Days Later.

Boyle is directing the first movie from a script by Alex Garland. Sony will release the film in theaters globally.

While plot details are vague, the original 28 Days Later in 2002 centered on a bicycle courier (played by Cillian Murphy) who wakes from a coma to discover the world had been overrun with zombies following the outbreak of a virus. The pic grossed more than $82 million worldwide and led to a 2007 sequel 28 Weeks Later, on which Boyle and Garland served solely as EPs.

Deadline recently broke the news that the studio has already tapped Candyman director Nia DaCosta to helm the second part of the trilogy, and that the plan is to shoot both films back to back.
