Brad Pitt's Got 'So Many Ideas' for a 'World War Z' Sequel. Great.

"World War Z" was pretty much just a big ole' mess — it took several drafts to script, cost oodles more than it was supposed to, had to be retooled by outsiders and even then it still didn't make a ton of sense at times — but audiences threw half a billion dollars at it, so of course a sequel is in the works. That's a zombie-style no-brainer.

According to Brad Pitt, though, the pedal's not quite to the metal on "World War Z 2" just yet because he wants to make sure they've got a few things straightened out before they go full throttle on the second installment to the Zed Apocalypse ... ya know, unlike last time.

Speaking to Variety, while promoting Oscar fodder "12 Years A Slave" at this year's Toronto International Film Festival, Pitt said of the "Z" sequel, "We're certainly talking about it, yes. We have so many ideas on the table from the time we spent just developing this one and figuring out how zombies work."

"We have so many ideas and so much information that we think we've got a lot of stuff to mine from," he continued. "So we're going to do our best and see what we get. We've gotta get the script right first to determine if we go further."

Sounds like someone's learned a lesson and is trying to escape the many plaguing problems of the first pic, and who could blame him?

Pitt's Plan B had boldly muscled out Leonardo DiCaprio's Appian Way for the rights to Max Brooks' thoughtful and nuanced novel with all the promise of a B.F.D. ... but then what came out was a generic, discombobulated actioner that many of the book's fans declared was only resemblant in title. Pitt even admitted the thing "barely got a fraction of the book in." If that.

And the problems didn't stop there, either. The movie's many production woes were so publicized and exposed — Damon Lindelof basically rewrote the movie's third act after everyone starting having a meltdown over the original cut — that just about any Joe Schmoe on the block could tell you at least a little something about what went wrong.

At the end of the day, though, what really counted were the ticket sales, and "World War Z" was Pitt's biggest box office hit ever (if you fudge the numbers and ignore how much was really spent, that is). So, basically, like it or not, if these "many ideas" hit paper to Pitt's expectations, the sequel is going to happen.

Hey, at least he wants a workable script done before the cameras start rolling this time. Progress?
