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).
