From The Telegraph, 15th Aug 2010:
Hong Kong director Christopher Sun is currently filming his $3.2 million '3-D Sex and Zen: Extreme Ecstasy', which is due for release in May 2011, but Italian director Tinto Brass has already announced he will produce a 3D remake of his 1979 erotic film Caligula.
Although mainland Chinese censors are almost certain to block the movie's screening, it has sparked wide interest in other Asian markets, including Japan and South Korea, as well Europe, and the United States.
Producer Stephen Shiu said: "This is the future of the movie business — it's human nature to want to see things in 3D."
Adding to the pressure, the American company Hustler is making a pornographic spoof of 3D science fiction blockbuster Avatar, the highest-grossing movie of all time and the film that heralded the beginning of the mainstream 3D boom.
