Tauriel
In June 2011 Peter Jackson announced that actress Evangeline Lilly, who played Kate Austen in the ABC drama Lost, was cast in the role. Lilly, had been a fan of Tolkien's books since she was 13, but was nervous about how Tolkien fans would react to  a character that did not appear in Tolkien's books. She stated that creating the character for the adaptation was the right thing to do, saying, "I believe she is authentic, because Tolkien refers to The Woodland Elves, he just doesn't talk about who they are specifically… [Peter and Fran] know that world so well. They’re not going to create a character that is not true to Tolkien's world." Despite this, some fans were unhappy with the creation of her character after the first trailer for the film was released on June 12, 2013.
