"However dark our night, however dim our hopes, the light will always follow darkness." So says a priest to young Louis Zamperini in the new trailer for World War II epic Unbroken. If today's new trailer is any indication, the biopic will exude that same sense spirit of triumph in the face of adversity.

Unbroken, directed by Angelina Jolie, tells the story of Olympic and war hero Zamperini, a track star who survived a plane crash and over two years in a Japanese internment camp. Zamperini, played by British actor Jack O'Connell, is all steely eyes and determination, powering through races and standing up to Japanese soldiers.

The trailer arrives one week after its subject passed away from pneumonia at the age of 97. Zamperini and Jolie reportedly grew close during production of the film, with the director calling his loss "impossible to describe" in a statement.

"We are all so grateful for how enriched our lives are for having known him," she said. "We will miss him terribly."

Distributor Universal Pictures is pushing the film as a tribute to the now-deceased hero. "We move forward to the release of Unbroken with a renewed sense of responsibility in bringing Louie's abundant life and indomitable spirit to the screen," the studio's statement read.

Unbroken will premiere in theaters Christmas Day.
