MUMBAI: The world’s first 3D adult film Sex and Zen: Extreme Ecstasy has been running to packed houses since it opened in Hong Kong last week. The scenario outside theatres showing the film saw packed audiences buying tickets priced three times the regular rates.

Adapted from the Chinese novel ‘The Carnal Prayer Mat, the film directed by Hong Kong-based director Christopher Suen, was promoted with the tag line ‘world’s first IMAX 3D erotic movie’.

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. The success of the concept has made some US adult movie makers explore the idea.

US-based pornographic magazine Hustler is in the process of making a 3D adult movie with Avatar like characters. Italian director Tinto Brass has announced that he would recreate his 1979 sex themed period film Caligula in 3D.

China has already banned Sex and Zen: Extreme Ecstasy and more countries are reported to follow suit.
