Chinese actress Zhang Ziyi brings her new film to the 17th Busan International Film Festival.

Zhang joined her "Dangerous Liaisons" co-stars in Seoul to speak to the media about her role, which she called "complex".

SOUDNBITE: Zhang Ziyi, actress, saying (Mandarin):

"Anybody should be happy to take this role, but it's very complicated to play this role. Through this movie, I felt actors and actresses should be impressed first (by the content of the movie) to impress audience."

"Dangerous Liaisons" is an adaptation of the famous French novel "Les Liaisons Dangereuses."

South Korean director Hur Jin-ho talked about the challenges of making the film.

SOUNDBITE: Hur Jin-hom, director, saying (Korean):

"As a Korean director, I had a burden to make a movie set in 1930's Shanghai. So I worried about it a lot in the beginning."

China started running "Dangerous Liaisons" on September 27 and South Korea will start screening it on October 11th.

This year's BIFF is set to run until October 13th and will feature 304 films, including world premiers, from 75 countries.
