Angelina Jolie wants to teach her children about the "strength of the human spirit".
The 38-year-old actress - who raises kids Maddox, 12, Pax, 10, Zahara, eight, Shiloh, seven, and twins Knox and Vivienne, five, with fiance Brad Pitt - has stepped behind the camera again for 'Unbroken', which tells the tale of World War II hero and former Olympic distance runner Louis Zamperini and she is hopeful the movie will send a positive message.
Angelina said: "For me, I think Louis has been very clear about what his message is. And I think, for my children, and for everybody in the world, I want to be able to say, it can seem dark, and it can seem hopeless, and it can seem very overwhelming, but the resilience and the strength of the human spirit is an extraordinary thing."
'Unbroken' marks Angelina's third venture into directing and she knew whatever project she took on had to mean something significant to her.
Speaking on the 'Today' show, she said: "I wanted to direct something again, but I just wasn't sure what. And it had to be something that I would love and care about, because it takes much more time away from your family, and much more effort than acting."
And the 'Maleficent' star - who lives in the same Los Angeles neighbourhood as Louis, 97 - felt a "responsibility" to the story because of the bond she forged with the war hero.
She said: "[It's] such a huge responsibility to get it right. Because I love [Louis] so much. And because he's helped me so much in my life."
