Angelina Jolie's movie about track star and WWII vet Louis Zamperini debuted its trailer today. This is the first full trailer for the movie Unbroken, which Jolie directed.

The Unbroken trailer features Irish actor Jack O'Connell, portraying Zamperini's incredible life. Zamperini participated in the 1936 Berlin Olympic games as part of the track and field team, and was talented enough to be noticed by Hitler himself.

The track star would then sign on to be part of the U.S. Army Air Corps, where his plane crashed in the Pacific Ocean in 1943. He was adrift at sea for more than 40 days before being captured by Japanese fishermen. He was them locked up for two years. Zamperini was tortured brutally during those years in prison.

He eventually made his way home to the U.S., and became a born-again Christian. He has been vocal about forgiveness for the remainder of his days.

Zamperini wrote two books about his life: published in 1956 and 2003, both were called "Devil at My Heels." His story was in the 2010 bestseller Unbroken, a book by Laura Hillenbrand.

Recently, Zamperini became good friends with Angelina Jolie, who is directing the movie version of his life.The two are also neighbors in Los Angeles.

Just this month, Zamperini passed away at age 93 after battling pneumonia for quite some time. Jolie released a statement about Zamperini shortly after his death, "It is a loss impossible to describe," the actress said in a statement. "We are all so grateful for how enriched our lives are for having known him. We will miss him terribly."

Unbroken is Jolie's second directorial effort, after helming the 2011 film, In the Land of Milk and Honey, which tackled the Bosnian war.

Already, the movie has been generating Oscar buzz for Angelina Jolie and the rest of the Unbroken team.

The movie, which has a screenplay written by Joel and Ethan Coen will be released in cinemas on Christmas day 2014.
