I realize that the usual studio approach to trailers is to emphasize the spectacle, especially when it comes to movies like this; but this looks insane. And not necessarily in a good way. These zombies are on steroids; or maybe we could call them super zombies!

In short, I'm not immediately sold. I need to see another trailer that's less frenetic. 

As someone who has not read the book that the film is based on, I don't really have any idea what to expect here; I know what the story is, but based on the many comments I've read on the web since the trailer was released last night, fans of the book aren't at all happy with what they see, with many of them saying that the footage looks absolutely nothing like what's described in the book. 

Then again, does that ever happen? This is director Marc Foster's own interpretation of the material. Whether or not it works won't be known with certainty until the film is out.

Stylistically, a review of the script I read compared it to Children Of Men, a film I love. I'm not sure I really get that vibe from this first trailer.

Brad Pitt stars as Gerry Lane, a worker at the United Nations, searching the globe for information that can stop a zombie outbreak that is bringing down nations.

By the way, I thought Anthony Mackie was in this; he was offered a part, but I guess no deal was worked out. 

I was surprised to see South African actor, Fana Mokoena, feature in the trailer. You may remember him from Safe House, Man On Ground and Hotel Rwanda.

But it's Brad Pitt starring and Marc Foster behind the camera, working from a beloved work of fiction, so I expect this will be one of the most talked about summer movies in 2013.
