Director Peter Jackson is in the midst of production on The Hobbit: An Unexpected Journey and The Hobbit: There and Back Again in New Zealand. According to actress Evangeline Lilly, who plays Tauriel in both adventures, the back-to-back shoot will take two years to complete.

"I still have to go back for five more months of filming. (I've been there) on and off for the past six months. It's a two-year shoot in total for both films, and my contract had me blocked off for about a year. I come in and out of New Zealand throughout that year."

She also spoke more about her character Tauriel, a Mirkwood elf who appears to be quite dangerous.

"Yes, she is a warrior. She's actually the head of the Elven guard. She's the big shot in the army. So she knows how to wield any weapon, but the primary weapons that she uses are a bow and arrow and two daggers. And she's lethal and deadly. You definitely wouldn't want to be caught in a dark alley next to Tauriel."

Evangeline Lilly also revealed she shows up near the end of The Hobbit: An Unexpected Journey, but has a larger role in The Hobbit: There and Back Again

"She's not in the first film very much. She comes into the first film near the end, and has a very small part to play. Her role in the second film is much more involved. Although, I have to say, when I first read the scripts and took the job, she had a lot less going on in the second film. I think the role is becoming a bit more demanding than I had expected it to be. There's a lot more for me to do now, which is a lot of fun, but it's a little more pressure."
