Let the zombie takeover continue.

The adaptation of Max Brooks' "World War Z," a novel recounting a zombie apocalypse from the first-hand accounts of those who survived it, is moving forward, now with Brad Pitt officially attached to the vehicle, MTV reports.

Pitt’s Plan B production company wrestled the rights to the project away from Leonardo DiCaprio’s Appian Way back in 2007, and while it was rumored that Pitt would play the lead, Brooks didn’t hear of Pitt's attachment until this year's preview night at Comic-Con.

“Quantum of Solace” director Marc Forster is still supposed to direct, and a revision of the script has been penned by "Lions for Lambs" writer/producer Matthew Michael Carnahan. The movie is aiming for a summer 2012 release.
