Actress Evangeline Lilly discussed playing the elf Tauriel in The Hobbit: The Desolation of Smaug, in the latest edition of Total Film magazine. This character does not appear in the J.R.R. Tolkien novel that director Peter Jackson's adaptation is based on, and the actress spoke about how "young" this character really is, as opposed to other elves such as Legolas and Thranduil.
"She's a very, very young elf. She's only 600 years old, unlike Legolas who's like, 1,900 years old and Thranduil who's about 3,000 years old. She doesn't have quite the wisdom and pose that those two boys do; she's a little more... gritty. A little more spontaneous, passionate perhaps."
The actress also spoke about the balance between her character's grace and her ruthless nature.
"To play this character I need to have a certain amount of grace]. But I'm also supposed to be an absolutely ruthless, deadly killer."
