First 3-D porn film

A group of Hong Kong filmmakers have started shooting what they claim will be the world's first 3D pornographic film.
No ordinary porn flick, "3-D Sex & Zen: Extreme Ecstasy" is being touted as the world's first IMAX-3-D erotic film.

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 producers are hoping the erotic period drama will prove a titillating hit with 3-D-glasses-wearing audiences and help develop a lucrative, niche film market.
