Kim So Yong

[on casting "Treeless Mountain"] "When I met Hee Yeon, I knew she would be perfect. She had this unusual self-confidence and strength. From our first interview, Hee Yeon challenged me in a way that young Korean children do not normally question authority. I discovered Song Hee, who plays Bin, through a photograph which was sent to me by my assistant in Korea. I fell in love with her face."
