The follow-up, titled "Unbroken: Path to Redemption" will be produced by Matt Baer, who also backed the original film, according to The Hollywood Reporter.
"Unbroken", about tortured World War II veteran Louis Zamperini, was directed by Angelina Jolie and featured Jack O'Connell as Zamperini, Miyavi as Mutsushiro Watanabe and Garrett Hedlund as John Fitzgerald.
The new film will explore the difficulty that the Olympian-turned-POW had in his private life after coming home.
