A group of Hong Kong filmmakers have started shooting what they claim will be the world's first 3D pornographic film.
The US$3.2mil (S$4.32 mil) 3-D Sex and Zen: Extreme Ecstasy has generated interest in a host of Asian film markets, as well as Europe and the US, the Sunday Morning Post reported.
Loosely based on a piece of classical Chinese erotic literature The Carnal Prayer Mat, the movie will star Japanese adult actresses Yukiko Suo and Saori Hara.
The film chronicles the story of a young man who, after being introduced to the erotic world of a duke, realises his ex-wife is the love of his life and features "orgies, swinging and some very graphic sex scenes".
Producer Stephen Shiu acknowledged that censors would likely block the movie's screening in mainland China, a key market for Hong Kong filmmakers.
"But we are almost closing deals with some markets including Japan, Korea, Southeast Asia and some pay TV channels in Hong Kong," he said.
