Ed Harris may join Brad Pitt in epic zombie apocalypse flick, World War Z, with Lost star Matthew Fox also apparently in talks, reports Deadline.

Brad Pitt and star of excellent AMC series The Killing Mirielle Enos are already set to star in the Marc Foster directed adaptation of the hugely popular Max Brooks novel, set ten years after zombies have infested the earth. Foster just worked on Machine Gun Preacher with Gerard Butler, which is getting great early buzz. 

The film has a massive budget of $125 million and will act as a tentpole next summer for studio, Paramount - who have just pushed Star Trek 2 back.
