Universal has unveiled the first trailer for Angelina Jolie‘s Unbroken, the true story of World War II hero and former Olympic long distance runner Louis Zamperini. Unbroken tracks the life of the young Olympian, who enlisted in the Air Force after war broke out in 1941. After his plane went down in the Pacific, Zamperini and two crew mates survived on a raft for 47 days before being taken prisoner by the Japanese. Last week Zamperini passed away at the age of 97. Universal first bought rights to Zamperini’s life story in the 1950s. It will finally hit theaters this Christmas. Unbroken stars Jack O’Connell, Garrett Hedlund, Domhnall Gleeson, Jai Courtney, Luke Treadaway, and Alex Russell and marks Jolie’s sophomore turn as director. Take a look:
