As we count down the days to the Boxing Day release of Unbroken, we sat down with two of its stars, Ross Anderson and Luke Treadaway.

We asked the pair what it was like working with Angelina Jolie, if it helped having such a British presence on set, and given the pair play prisoners of war, how they went about researching the roles and losing the weight required.

Unbroken is released on December 26th. Watch our interviews with other cast members Jack O’Connell here, and Miyavi here.
