EXCLUSIVE Angelina Jolie is starting to cast the players in “Unbroken,” her second directing effort. The film was written by Joel and Ethan Coen, with a polish by William Nicholson (“The Departed”). Jolie, I’m told, has cast Finn Wittrock to join Jack O’Connell in the World War II thriller. O’Connell plays Louis Zamperini, an Olympic runner who was taken prisoner by the Japanese forces during the war. Wittrock will play one of the soldiers in Zamperini’s outfit. Wittrock is currently filming “The Normal Heart” for HBO. Two seasons ago on Broadway he played Happy in Mike Nichols’ “Death of A Salesman” with Philip Seymour Hoffman and Andrew Garfield. “Unbroken” starts filming in early 2014.
