But it wasn't just the $65-million budget and the historical sweep of "Unbroken" that concerned the actress turned filmmaker (Jolie has since directed herself and husband Brad Pitt in the domestic drama "By the Sea," which she also wrote).
Jolie said she felt a personal allegiance to Zamperini, who died earlier this year at age 97, and not just because they were Hollywood Hills neighbors. She truly admired the man who survived 47 days on a life raft and endured more than two years of torture in Japanese prisoner of war camps — and still overflowed with compassion and forgiveness.
"I would go out of my way to spend time [with him]," Jolie said recently. "I'd wake up in the morning and all I'd want to do is go over to Louis' house. I'd rather be with Louie than anybody."
Why did this story mean so much to you?
It's something that we need as human beings: to see somebody confronted with so many obstacles in life and refuse to go down and not only stand back up but somehow find a way to love and live again, and be full of usefulness and joy."
You eliminate the latter chapters in the book, after Zamperini comes home from the war and undergoes a religious conversion. So you tried to hint at the role faith played throughout his life.
It was actually more disrespectful to try to jam that into the last 15 minutes. It actually felt more respectful to say, "These are not sudden themes, and this is not something that's just an element of his life. This is present from the little teeny boy we see in church all the way through."
You also decide to show how badly Japanese civilians are suffering during the war.
I know it was important to Louie. You're so focused on the enemy that when you step back and you see the civilian casualty on both sides, and you understand what is happening, it changes the way you view your enemy. You see something deeper, you see a country, and a people, and mothers and fathers, and it's not so black and white.
What were your thoughts about how graphically you would depict the torture?
We wanted the movie to be PG-13, which it is, because I have a 13-year-old boy, and whether it be video games or certain kinds of films, they see a lot of horrors. But it's important to understand the real situations in life, the real history. We wanted it to be true to history that would be hard enough that we were respecting what really happened. Because if you go too light, you're not paying respect to the reality of history. And if you show too much, you make people turn away and they can't absorb the information.
How and where do you think you need to grow as a filmmaker?
