Jolie is directing the project centering on World War II survivor Lou Zamperini.
The Coen brothers have been tapped to rewrite Unbroken, the adaptation of Laura Hillenbrand’s 2010 book, for Universal -- which has been trying to mount a Zamperini story in some form or fashion for decades.
Universal picked up the rights to the book in January 2011, initially for Francis Lawrence to direct. Jolie boarded as director in December. She has spent weeks searching for top-flight writers to tackle the project, with sources saying the director was extremely choosy.
