“LOST” starlet Evangeline Lilly is going full-elf in Peter Jackson’s adaptation of J.R.R. Tolkien’s The Hobbit. The 31-year-old stunner recently spoke to SFX about playing Tauriel, a woodland elf not originally found in Tolkien’s novel.

She says:

With every film, you have to educate yourself on the material and it’s often things you don’t know a lot about. Right now I’m studying Elvish and having conversations with people about learning how to be an archer, a swordsperson and how to fight like an elf instead of a gritty convict [laughs].

The Hobbit will be split into two movies: The Hobbit: An Unexpected Journey (release date: Dec. 14, 2012) and The Hobbit: There and Back Again (release date: Dec. 13, 2013). Production is currently underway in New Zealand.

Lilly, best known for playing fugitive Kate Austin on ABC’s “LOST,” will soon be seen in DreamWorks upcoming Hugh Jackman vehicle Real Steel, opening Oct. 7.
