The Coen Brothers Are "Unbroken"

Joel and Joel Coen are teaming up with director Angelina Jolie on "Unbroken," as writers says THR

Based on author Laura Hillenbrand's 2010 bestselling biography, that chronicles the life of Olympic athlete Louis Zamperini . He was captured by the Japanese navy and detained at a P.O.W. camp. That came AFTER he survived both a near-fatal plane crash and being stuck on a raft for 47 days.

"Les Miserables" writer William Nicholson penned the latest script draft for the pic. Richard Lagravenese worked on the script before that, but with Jolie now in the big chair a new draft was needed and she managed to convince the Coens to do it.

Jolie came onboard as director in December, replacing the previously linked Francis Lawrence.

Matthew Baer ("The Replacement Killers") and Erwin Stoff ("The Blind Side") are producing with Jolie.
