Jolie next completed her second directorial venture, "Unbroken" (2014), about World War II hero Louis Zamperini (1917–2014), a former Olympic track star who survived a plane crash over sea and spent two years in a Japanese prisoner-of-war camp. She also served as producer under her Jolie Pas banner. "Unbroken" is based on Laura Hillenbrand's , the film was scripted by the Coen brothers and starred Jack O'Connell. After a positive early reception, "Unbroken" was considered a likely Best Picture and Best Director contender, but it ultimately received mixed reviews and little award recognition, though it was named one of the best films of the year by the National Board of Review and the American Film Institute. "Variety" magazines Justin Chang noted the film's "impeccable craftsmanship and sober restraint", but deemed it "an extraordinary story told in dutiful, unexceptional terms." Financially, "Unbroken" far outperformed industry expectations in its opening weekend, eventually earning over $163 million worldwide.
