Brad Pitt tells his band of soldiers "you think it can't get worse, it can and it will" in the first trailer for his hotly anticipated next film, Fury. Set in the final months of WWII, Fury follows Brad's battle-weary sergeant Wardaddy and his tank which often goes behind enemy lines for the Allies.SCROLL DOWN FOR VIDEO Brad Pitt stars in new WWII film Fury In the heart of Nazi Germany, the film introduces a new assistant driver to the team, played by Logan Lerman, and the trailer takes the viewer on a journey with these five men. "Ideals are peaceful, history is violent," Wardaddy tells his men, and this two-and-half minute long trailer aims to show just how violent and dark WWII was. Filmed entirely in the British countryside, the film is directed by David Ayer and also stars The Walking Dead's Jon Bernthal, The Avengers' Mark Ruffalo, and Shia LaBeouf. In order to maintain authenticity, a British D-Day veteran was personally invited to the set by Brad. Peter Comfort, 90, met the Hollywood superstar but admitted he had to use Google before hand to find out who Brad was. "Mr Pitt was very friendly and charming actually but I didn't know who he was," the WWII veteran said. Peter, the last survivor of the 13/18th Royal Hussars, was signed up to the Sherman tanks at the age of 21. Brad wanted to ask him what life was like inside the tanks. He landed at Sword beach on D-Day, 6 June 1944 on a day which saw 140 of his fellow soldiers killed and 350 more wounded. "My regiment, the Light Dragoons, got in contact with me about three weeks ago," Peter explained. "They'd been approached by an ex-officer who worked for a film company and asked if there were any old boys left. Then Brad Pitt phoned me and said he wanted to speak about Sherman tanks for a film. Peter added: "He talked me into going and, I have to say, I was extremely well treated. They wanted a lot of information to make it accurate and fired a lot of questions at me. Luckily there weren't any questions I didn't know the answer to." A grandfather-of-six, Peter said: "The film crew got me up on the tank for a few pictures and wanted to know everything about it. They wanted to know where we slept, where we spent a penny, the living conditions and what it was like in action, so I told them. "I don't like to talk about it because I saw too many people killed but Mr Pitt was very nice and I will be interested to see the film."
