Dobrev: 'Playing two roles is challenge'

Nina Dobrev has revealed that playing two roles on The Vampire Diaries is a challenge.

Dobrev stars as both Elena and Katherine in the show and told DS that she enjoys the opportunity.

"It's kind of confusing," she said. "But it's exactly what I want. It's the biggest, most welcome challenge."

Dobrev added that Elena and Katherine are completely different characters.

"Both characters are very multi-dimensional and layered and complicated and flawed," she said. "One is very sweet and a girl next door who has issues and tries to deal with them to the best of her abilities. And she has a lot of pressure coming from different directions but somehow manages to plough through and protects everyone and rises to the occasion when it's difficult. She's very strong and courageous, I think, and I admire her persistence.

"But at the same time, Katherine is this kind of twisted, maniac, crazy, narcissistic, selfish, vampire, bloodthirsty killer who sees the world as her gourmet buffet and she just has to have a taste of every single flavour, so she does."
