Angelina Jolie surgery sparks surge in female cancer tests: study

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

The film is based on the best-selling 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.

The actress also disclosed her feelings about marriage after her surprise August wedding to Pitt at their French estate Chateau Miraval.

"It does feel different," she said. "It feels nice."

The mother of six also revealed that her children wrote the couple's marriage vows.

"They did not expect us never to fight, but they made us promise to always say, 'Sorry,' if we do. So they said, 'Do you?,' and we said, 'We do!'"

The December issue of Vanity Fair will be available in New York and Los Angeles on Nov.6 and across the country on Nov 11.
