Brad Pitt cracked up laughing when he met a World War II veteran serving as consultant on new movie Fury because the 90 year old had never heard of the Hollywood superstar. The actor personally invited Peter Comfort to the U.K. set to watch him shoot the movie, in which the actor stars as a tank corps commander close to the end of the Second World War. Pitt was eager to hear all about the former tank driver's experiences, but he was in for a surprise when he came face-to-face with the Brit. Comfort says, "Mr. Pitt was very friendly and charming actually but I didn't know who he was. I said to him, 'Until last night I didn't have a clue who you were and then I googled you and you've been in quite a lot of films.' They all rolled about laughing when I said that." The war hero felt honoured to give advice to the filmmakers, adding, "They wanted a lot of information to make it accurate. They wanted to know where we slept, where we spent a penny (urinated), the living conditions and what it was like in action. There weren't many questions I couldn't answer. I'll be interested to see the film." The grandfather-of-six has been invited to attend the British premiere of Fury next year (14).
