Hollywood star Brad Pitt has said playing a US army officer in his new movie Fury has helped him to be a "better father".
The World War Z actor, who has six children with wife Angelina Jolie, plays US Sergeant Don "Wardaddy" Collier in the Second World War film.
"I learnt a lot from this film. We all walked away absolutely enriched," the actor said ahead of the film's European premiere in London.
"This role is a real study in leadership and learning to command respect and because of this, I am now a better father."
Hunger He added: "This film is about the soldiers' exhaustion from the cold, hunger and the accumulative effect on a daily basis. We took that to heart. I hope the soldiers will walk away from this and feel they are recognised."
The film follows the five-man crew of a Sherman tank called Fury in the European Theatre of war in April 1945 as the Allies head into Nazi Germany.
Pitt (50), who was referred to as "Top Dog" on set, admitted he got rather attached to his vehicle.
