"Unbroken" star Jack O'Connell says filming left him broken

STORY: Rising British star Jack O'Connell and first time Japanese actor Miyavi are the leads in Angelina Jolie's new World War II movie, the making of which O'Connell says left him feeling 'broken'. Based on a best-selling book by Laura Hillenbrand, 'Unbroken' tells how Louis Zamperini, an Olympic sprinter played by Jack O'Connell, spent 47 days on a life raft after his plane crashed into the Pacific and was then held for two years by the Japanese. The film contains scenes in which Zamperini is repeatedly beaten by a brutal Japanese prison guard played by the pop singer and songwriter Miyavi and is already the subject of Oscar buzz as a contender for Best Picture. Miyavi said he stayed away from O'Connell while on set as he felt it was important to keep a distance. 'Unbroken' is released in the United States on December 25 and in the UK on December 26.
