Deadline is reporting that four-time Academy Award nominee Ed Harris and LOST star Matthew Fox are in talks to join the cast of World War Z, the Paramount Pictures movie adaptation of the popular book of the same name by Max Brooks.

The two actors would join Brad Pitt, who’s been attached to the project for a long while now. The movie has faced many setbacks over the course of its journey to the big screen, but is ready to begin production later this month.

World War Z tells the story of a post-apocalyptic world overrun by zombies, as told told from the first–hand accounts of the people trying to survive.

In addition to LOST, Fox has appeared in movies like Smokin’ Aces, We Are Marshall, and Speed Racer. Harris has of course appeared in a seemingly endless amount of great films, including Apollo 13, A Beautiful Mind, The Rock, and A History of Violence, among many others.

World War Z will be directed by Marc Forster, whose previous credits include Monster’s Ball, Finding Neverland, and Quantum of Solace.

No release date is officially set, but the hope is for the movie to possibly arrive next summer.
