Filming has begun on Unbroken: Path to Redemption, the true story that will serve as a stand-alone tale and follow the events of 2014’s three-time Academy Award-nominated film Unbroken. Unbroken: Path to Redemption tells the tale of Louis “Louie” Zamperini’s post-World War II struggle to find peace and forgiveness after his brutal treatment as a Japanese prisoner of war.

Both Unbroken and Unbroken: Path to Redemption are based on Laura Hillenbrand’s best-selling book, Unbroken, which spent more than four years on The New York Times best-seller list in hardcover, including 15 weeks at No. 1. The film Unbroken opened to the third-best Christmas Day opening of all time before going on to make almost $165 million worldwide.

Unbroken: Path to Redemption stars Samuel Hunt (Chicago P.D.) as Zamperini; Merritt Patterson (The Royals) as his wife, Cynthia; and Will Graham as his own grandfather, evangelist Billy Graham. The film is produced by The WTA Group in partnership with Universal 1440 Entertainment, with theatrical release through Pure Flix.
