The incredible true story of Louis Zamperini (Jack O'Connell) comes to life on the big screen in an international trailer for director Angelina Jolie's Unbroken, arriving in theaters on Christmas Day.

This new footage shows flashbacks to Louis' troubled upbringing and his rise to become an Olympic track champion, years before his plane was shot down in World War II. Louis, along with two other crewmen, survived in a raft for 47 days after a near-fatal plane crash in WWII-only to be caught by the Japanese Navy and sent to a prisoner-of-war camp.

Adapted from Laura Hillenbrand's (Seabiscuit: An American Legend) enormously popular book, Unbroken brings to the big screen Zamperini's unbelievable and inspiring true story about the resilient power of the human spirit.

Domhnall Gleeson, Finn Wittrock, Garrett Hedlund and Jai Courtney co-star in this powerful adaptation about the power of the human spirit, arriving in theaters Christmas Day.
