It was an emotional rollercoaster for Angelina Jolie at the world premiere of her new film "Unbroken." The actress and husband Brad Pitt made their first public appearance together as a married couple at the splashy Sydney event, where Jolie's second narrative feature — about U.S. Olympic track star and WWII hero Louis Zamperini — reportedly drew gasps from the audience during one particularly brutal moment. The film depicts Zamperini's (played by "300: Rise of an Empire" star Jack O'Connell) struggle to survive in several Japanese P.O.W. camps, where he was imprisoned and systematically tortured after surviving for 47 days at sea following a plane crash.

Jolie, who shot the film entirely in Australia, became visibly choked up when confronted with a quote by Zamperini, who, prior to his death in July at the age of 97, stated that Jolie "became a great part of my life, she knows what she wants and she knows what she's doing and I trust her one hundred per cent. I have all the confidence in the world that 'Unbroken' will be a great film." (clip via the Daily Mail)

Based on the 2010 nonfiction book "Unbroken: A World War II Story of Survival, Resilience, and Redemption" by Lauren Hillebrand, the Oscar-buzzed film was written by Joel and Ethan Coen, Richard LaGravenese and William Nicholson. It hits U.S. theaters on December 25.
