Tauriel

Tauriel is a fictional character from Peter Jackson's feature film adaptation of J.R.R. Tolkien's The Hobbit. The character does not appear in the original book, but was created by Peter Jackson, Philippa Boyens and Fran Walsh as an expansion of material adapted from the book, and first appears in the second and third films in that trilogy, The Hobbit: The Desolation of Smaug and The Hobbit: The Battle of the Five Armies.[1] She is a Woodland Elf whose name has been translated as "Daughter of the forest", and is the head of the Mirkwood Elven guard. She is played by Canadian actress Evangeline Lilly, who was nominated for several awards for her performance in The Desolation of Smaug, with some of the stunt work performed by Australian stuntwoman Ingrid Kleinig.
