Director Dae-woo Kim has stated that one of the requirements to play the characters "Choon Hyang" and "Hyang Dan-i" would be scenes involving nudity. Many prominent South Korean actresses had considered appearing in the film but later declined because of the many sexual scenes. Eventually, Cho Yeo-jeong and Ryu Hyun-kyung were selected as heroines of the film. Their contract stipulated that they had to show their breasts, but it was later decided that their butts should also be exposed.
