Academy award-winning actress Angelina Jolie is “open” to pursuing a life in politics, diplomacy or public service, she told Vanity Fair magazine.

Jolie, who won a best supporting actress Oscar award for her role in Girl, Interrupted, has turned her hand to directing. Her latest film behind the camera, Unbroken, about Olympic runner, World War II airman and prisoner of war Louis Zamperini, is set to open on December 25.

Brad Pitt’s wife and a special envoy to the UN High Commissioner for Refugees (UNHCR) said that her work as a humanitarian has made her conscious of the fact that politics have to be considered as an option.

I don’t know in what role I would be more useful

“Because if you really want to make an extreme change, then you have a responsibility,” she told the magazine. “But I honestly don’t know in what role I would be more useful – I am conscious of what I do for a living, and that (could) make it less possible.”

When the conversation turned to her film, Jolie, 39, broke down in tears as she told the magazine about her friendship with Zamperini. She showed the former Olympic athlete and war hero an early cut of the movie before he died in July at the age of 97 after a 40-day bout of pneumonia.

“It was an extremely moving experience,” Jolie said, “to watch someone watching their own life.”

The film is based on the bestselling book Unbroken by author Laura Hillenbrand about the life of Zamperini. He spent 47 days in a life raft after his plane crashed into the Pacific and two years as a prisoner of war under the Japanese. Jolie said she and Zamperini talked about his faith and that after a life of fighting, he said his death would bring him peace.
