Evangeline Lilly Goes Full Bad-ass In This Hobbit: Desolation Of Smaug Behind-The-Scenes Clip

She may have battled polar bears, erstwhile beardy suitors and psychic-gobbling smoke monsters during her time on TV mega-smash Lost, but it's clear from our exclusive behind-the-scenes clip that working on The Hobbit: The Desolation of Smaug was a whole new challenge for Evangeline Lilly.

Watch her learn the knifey ropes in our exclusive clip, and her burgeoning competitiveness with her elf companion Legolas, played by Orlando Bloom.

The Hobbit: The Desolation of Smaug is available to own on DVD and Blu-ray from November 3rd 2014.
