The decision to bring over three AV porn stars from Japan to star in the film was really a first, grabbing people's attention and generating interest in the actors themselves. So here's the list of actors; don't miss out, folks.
Director Qian Wenqi was previously Wong Jing's assistant director, having filmed "Yupu Chuan 2", "Peaches Ripen 2 & 3", "Ten Evil Techniques of Nanyang" and other films. Due to the recent slump in Hong Kong sex films, nude stars have moved on, and newcomers with market potential can now be counted on one hand. Thus, many Hong Kong producers have set their sights on Japan across the sea. The Japanese AV industry is flourishing, with many female porn stars willing to take risks at prices that satisfy Hong Kong producers. For example, earlier in "Passion", starring Louis Koo and Eason Chan, as well as in Pang Ho-Cheung's "AV", the scenes featuring nudity were performed by Japanese AV porn stars.
