"Unbroken": First trailer for Angelina Jolie's Louis Zamperini biopic

A stirring new trailer has arrived for "Unbroken," the Angelina Jolie-directed film about Olympian and World War II hero Louis Zamperini.

Zamperini, who died last week at the age of 97, was a long-distance runner who competed at the 1936 Berlin Olympics before enlisting in the Air Force during World War II. He survived 47 days on a raft in the Pacific Ocean after his bomber crashed and then endured two years in Japanese prison camps.

The film, based on Lauren Hillenbrand's book of the same name, stars Jack O'Connell as Zamperini alongside Garrett Hedlund, Domhnall Gleeson, Jai Courtney, Luke Treadaway and Alex Russell.

It's also Jolie's second turn in the director's chair, following her directorial debut "In the Land of Blood and Honey."

"Unbroken" hits theaters on Christmas Day. Watch the trailer below:
