Angelina Jolie has hailed Brad Pitt a ''great man''.

The 39-year-old actress admits her life with her actor husband - with who she raises children Maddox, 13, Pax, 10, Zahara, nine, Shiloh, eight, and twins Knox and Vivienne, six - helped influence her work on 'Unbroken', her latest directorial effort about the real-life tale of Louis Zamperini, an Olympian who was taken prisoner by Japanese forces during World War II.

She said: ''['Unbroken'] is an epic about the human spirit, so I think certainly in knowing, less about the technical aspect of shooting a war film, but more what I know of him [Brad] as a man and living with this great man and seeing the choices he makes with our family, our children, the way he treats me and the values he holds and learning from my sons.

''These are things I think I brought to the film that I understand about men and what I love about men, and what I think I'd want our generation to be reminded of.

''The great men who came before them and the greatness in them now and how to rise up to it.''

While shooting 'Unbroken' in Australia last year, Angelina adopted a number of local expressions and admits it was always a pleasure to hear the phrase ''No worries''.

Speaking at a press conference for the film in Sydney today (18.11.14), she said: '''No worries' is a great thing to hear from your crew,

''When you're in the middle of 200 extras and there's a lot to do sinking planes in the water in a very very stressful shoot and you say, 'Can we do this?' and they say, 'No worries'. ''
