Brad Pitt's World War Z is being considered as a potential trilogy. Director Marc Foster and Paramount Pictures are both thought to view the post-apocalyptic horror film as a trilogy, which could see the 48-year-old star finally get a big movie franchise of his own.

The motion picture - which is set to be released later this year - sees Brad portray the role of a United Nations fact-finder and family man who travels around the world to visit survivors of a zombie apocalypse which is referred to as World War Z. Should the film be turned into a trilogy, it is thought it will take on the same realism of Matt Damon's Bourne series.

Brad recently starred as Billy Beane in baseball drama movie Moneyball and director Bennett Miller - who stepped in following the summer 2009 departure of Steven Soderbergh, who had been developing the script for two years - found the Hollywood actor's experience on both sides of the camera to be invaluable: "You work all day with Brad the actor and there's that energy, and then we'd wrap at the end of the day and maybe half an hour later we'd get together in this little area outside his trailer and he'd be Brad the producer. We would look at the next day, just go over things and maybe have a glass of wine. Sometimes it would be two or three hours of discussing and planning, and it's pretty exhausting making a movie, but it became this ritual for us. And then early the next morning, Brad the actor is back, being on set and making things happen in a totally different way."
