Screenwriter Alex Garland suggests a sequel to 2007's 28 Weeks Later could be on its way.

“We’ve just started talking about it seriously” Garland, who's making his directorial debut with Ex Machina, tells IGN. “We’ve got an idea. Danny [Boyle] and [producer] Andrew [Macdonald] and I have been having quite serious conversations about it, so it is a possibility. It’s complicated. There’s a whole bunch of reasons why it’s complicated, which are boring so I won’t go into, but there’s a possibility.”

Directed by Boyles from a script by Garland (who wrote the 1996 novel The Beach), the 2002 post-apocalyptic horror film 28 Days Later centers on a man who wkes up in a hospital after the outbreak of "Rage," a virus that turns those infected into horrendous beasts. 28 Weeks Later , which was directed by Juan Carlos Fresnadillo (Intruders), reintroduced Rage to a seemingly virus-free Great Britain.

In 2010, after helming 127 Hours, Boyle expressed interest in directing the third film in the horror franchise. It sounds like he might still be involved as more than a producer.

Garland added that following the pattern of time established by the first two films makes sense from a few different perspectives. "It’s more likely to be 28 Months than 28 Years," he said. "28 Years gives you one more place to go. 28 Decades is probably taking the piss."
