It's not quite Venice or Cannes, but Twins member Charlene Choi Cheuk-yin made a bit of a mark on the international film festival scene last week. The Canto-idol was voted best actress at this year's 11th annual Puchon International Fantastic Film Festival in South Korea for her performance in Oxide Pang Chun's new spooker, Diary. Choi (pictured in a movie still with Shawn Yue Man-lok) plays a psychotic woman searching for her boyfriend. 'When I was told about the news, I was shocked and I called a lot of people to check if it was for real,' Choi said. The Puchon festival focuses on genre works of a love, fantasy and adventure nature, far more audience oriented than other more high-minded artistic showcases. Choi said her success was a result of lessons with her Simply Actors co-star Jim Chim Sui-man. 'I really want to say thank you to my teacher, 'Jim Sir'. He helped me improve on my acting a lot.' Now, if we can just find her a voice coach for singing.
