How long are "the infected" going to be around?  28 Days Later screenwriter Alex Garland, who's currently promoting the release of his directorial debut Ex Machina, says "quite serious conversations" are underway with director Danny Boyle and producer Andrew Macdonald about 28 Months Later.  The original movie begins with a man (Cillian Murphy) waking up to discover that world has been ravaged by zombies (although they're never referred to as "zombies").  The 2007 sequel, 28 Weeks Later, focused on the U.S. military attempting to re-populate a small area of London, but it doesn't go smoothly.

So what happens over two years later?  Hit the jump for more.

Speaking to IGN, Garland says they haven't reached the script phase, but:

"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."

Bore us, Mr. Garland.  You might be surprised about what we find interesting.

Garland, who would probably serve in an executive producer capacity like he did on 28 Weeks Later, notes that the sequel isn't even officially titled "28 Months Later", although he sees that as the natural next stage of the franchise:

“It’s more likely to be 28 Months than 28 Years” he revealed. “28 Years gives you one more place to go. 28 Decades is probably taking the piss.”

Let's not stop there.  I want to see 28 Centuries Later.  All hail the zombies of 4815.
