Kristen Stewart stars alongside Charlize Theron and Chris Hemsworth in a modern fairytale with a twist, Snow White and the Huntsman.
Stewart revealed that she was "destroyed" by the part, which she said was the most physically demanding role of her career.
Co-star Hemsworth admitted he had suffered from Stewart's strength after he was struck with an accidental "big right hook" from the star while filming.
The BBC's Tim Masters spoke to the stars of the film.
