Which actress played Tauriel in "The Hobbit" film series directed by Peter Jackson?

Nicole Evangeline Lilly (born August 3, 1979) is a Canadian actress and author who came to prominence for her starring role as Kate Austen in the ABC series "Lost" (2004–10), for which she won a Screen Actors Guild Award and received a Golden Globe Award nomination. She is also known for her roles as Connie James in "The Hurt Locker" (2008) and Bailey Tallet in "Real Steel" (2011)

In 2012, Lilly was cast as the Mirkwood elf Tauriel in Peter Jackson's three-part adaptation of J. R. R. Tolkien's "The Hobbit". The character, which does not appear in the original book by Tolkien, was created by Peter Jackson and Fran Walsh as the head of the Elven guard who wields a bow and two daggers as weapons. Lilly, who had been a fan of Tolkien's books since she was 13, underwent training for swordplay and archery, as well as in the Elvish language for the role.
