Actors Brad Pitt and Shia LaBeouf have spent some man-to-man time in an English woodland as a rather unique bonding exercise dreamed up by David Ayer, director of the WWII movie they're currently filming, reveals a source speaking to Us Magazine.

The actors were also joined by other members of the Fury cast who will play a close-knot group of soldiers in the upcoming movie, including Logan Lerman, 21, Jon Bernthal, 37, and Kevin Vance. "They play soldiers in the same World War II troop and the director wanted to make sure they bonded. So he dropped them in the wilderness - without their cellphones!" said the source.

The group spent three nights out in the Buckinghamshire woods from the 16-19th September and had to look for their own food and set up camp together so their onscreen acting as a tight military unit would be believable. In addition to the camping trip, the actors have also been given training with tanks and machine guns at the National Training Center in Fort Irwin, California.

Many would give their right arm to be spooned up against World War Z actor Pitt to keep warm in a chilly tent in the middle of the forest. Indeed, the source teased "They must have gotten pretty cosy in the tents they were sharing."

Fury will also star Clint Eastwood's son, Scott, who didn't participate in the camping trip but has been seen flexing his sizeable muscles whilst undergoing tank training in the US. The rising 27 year-old star is trying to make his name away from his father's legacy and has said he likes "being under the radar" and even admitted to having auditioned with the surname "Reeves" so no one would clock who he was.

Set in 1945, the film will follow a five-man tank crew who "must mount a last offence against the Nazi forces as the regime begins to crumble," according to Digital Spy.

Fury will be released on the 14th November 2014.
