28 Days Later is without a doubt one of the most influential zombie movies ever made. Although released in 2002, way after George Romero's cult classic Night of the Living Dead or his films which followed, Danny Boyle's masterpiece has shaped the zombie culture in ways other movies dream of.
With the sequel 28 Weeks Later coming out in 2007, we've been over 10 years now without another in the series. And although it's been reported over the years that a third film was in the works, writer of the first, Alex Garland, has just shot down the possibility.
Since 28 Days Later, Garland has written screenplays for Never Let Me Go, Dredd, and his original Ex Machina. Although he's stayed with the disturbing, sci-fi vibe, it seems he might be done with zombie films.
Let's hope this isn't a definitive answer, but in the meantime, check out Garland's new film Annihilation starring Natalie Portman, in theaters February 23, 2018.
