Han Hyo Joo talks about playing her first ever villainous role

The actress said, "The So Yul (her character in the movie) that I acted was not a villainous role in my mind. Because the situations [in the movie] were so dire and because she had no other choices, she was forced to do the things she did. I was shocked myself. I was thinking that I had sides and expressions to me that even I've never seen before. In one way, I think it was a new challenge at acting."

Han Hyo Joo added, "There were many times that I felt pained in order to express that. It was not an easy filming process. So I'm curious what [people] will think of it and how they will view the Jung So Yul that I portrayed." 

I guess we'll have to see the movie for ourselves when it hits theaters on April 13!
