Evangeline Lilly struggled to film action scenes in the upcoming Hobbit sequel as her elf wig would get tangled in her weapon props.

The Lost star plays elf warrior Tauriel in the film and she told the New York Daily News that she enjoyed working on the movie but the only downside was the 9kg wig she had to wear.

"The wig was incredibly painful when I had to do my stunts. It also gets caught in everything. I would get my weapons caught in my hair. I would get props caught in my hair. It was really hazardous."

The Hobbit: The Desolation of Smaug hits our screen on December 13, 2013.
