"Warner Bros. Pictures has bought Colin Trevorrow's script World War X and has set it up with Silver Pictures.
The trade says the story is 'centered on a man recruited by a team of government agents to stop a terrorist from the future who is using time travel to reshape history'
Joel Silver and Andrew Rona are producing. Chris Bender, JC Spink, Alex Heineman and Jake Weiner are executive producing."
Sounds like a great story. Original even! I love time travel stories and this sounds like a new take on the concept.
