If there's one thing that's more inevitable than a PG-13 remake of a classic horror flick, it's a sequel to an "out of nowhere" horror hit. And yes, I most definitely consider Danny Boyle's 28 Days Later to be (at least partially) a horror flick, although I have a few geek friends who love to argue about that. And we all know the drill by now: We hear that something called 28 Weeks Later is in production and we get really conflicted. On one hand, another dose of infected terror could be a real hoot; on the other, we really hate it when we see lame-o sequels spawned from really solid genre flicks.

The good news is that, based on what I've seen and heard regarding 28 Weeks Later, we just might be in for a gruesome good time. And if you'd like a nifty little taste of what's in store for a post-apocalyptic London, then by all means check out this brand-new trailer for the sequel. (Before yesterday you could only see this clip if you went to see The Hills Have Eyes 2, and while it's a pretty good trailer, I don't really consider that a fair trade-off.) Helmed by Intacto director Juan Carlos Fresnadillo, the follow-up stars folks like Robert Carlyle, Rose Byrne, Jeremy Renner, Harold Perrineau and Catherine McCormack and it opens wide on May 11.

You're in for a treat; the teaser trailer for the next great zombie flick has been released. From what I can tell, 28 Weeks Later has a lot of running, fires and the oh-so strong heroic character out to save the human race. I love it. I have to admit that I was slightly disappointed when I learned that Danny Boyle would not be directing. 28 Days Later was truly an exquisite film on many levels; lighting, acting and composition were gorgeous. One of my favorite images was Cillian Murphy walking alone in the wilds of his newly emptied Britain; the magnitude of his size against the impending doom was paralleled to the massiveness of the commercial truck shadowed against him. Magnificent.

Although Boyle is not directing, he is producing the film -- Juan Carlos Fresnadillo will take the torch to direct. Fresnadillo is in fact an Oscar nominated filmmaker for his short film Esposadas in 1996 and he's also partially responsible for the writing credits of 28 Weeks Later alongside Rowan Joffee. What are we basically in for? Well Britain has fallen, there isn't a living person inhabiting its streets. Thus America decides to come to the rescue ... but can the American army prove stronger than the zombie race? The full trailer will appear starting March 23 in theatres before The Hills Have Eyes II.

We already brought you the news that the 28 Days Later sequel (cleverly titled 28 Weeks Later) was about to get underway over at Fox Atomic, and early reports indicated that both Jeremy Renner and Harold Perrineau were on board to star.

Now, thanks to a Fox press release located at ComingSoon.net, I can share a bunch more news. The sequel, which is being produced by the writer/director/producer team of Garland, Boyle and Macdonald, is being directed by Juan Carlos Fresnadillo (Intacto). Production just got underway in England this past week, and that's why we're getting the scoop on the full cast. An impressive one, too! In addition to Renner and Perrineau, 28 Weeks Later will also feature the always-great Robert Carlyle (Trainspotting), the rather lovely Rose Byrne (Attack of the Clones), the also-gorgeous Catherine McCormack (Braveheart), and young Imogen Poots, who was last seen in V for Vendetta.

The sequel picks up six months after the terror of 28 Days Later, and it sees the U.S. military making the (erroneous) claim that the virus is now dead and gone. But without the virus, we'd have no sequel. Fox Atomic is aiming to have 28 Weeks Later ready for release on May 11th of next year.
