Brad Pitt and Shia LaBeouf got back to basics as they reportedly enjoyed a camping trip in the British wilderness, as part of a bonding exercise for their new film, Fury.
The two actors had to give up their mobile phones and forage for food as they spent three days in a desolate forest in September in Buckinghamshire on director David Ayer's orders, reported the Daily Mirror.
Brad plays a Sherman tank commander of an American tank called Fury in the World War II drama, with Shia as one of his crew members.
Logan Lerman, Michael Pena and Scott Eastwood are also set to have roles in the film.
Written and directed by the End Of Watch filmmaker David, the story takes place in 1945 as the Nazi regime collapses, and the five-man tank crew battles the German army.
Shooting is set to start in September, in time for a release date in winter 2014.
