Sex and Zen: Extreme Ecstasy

3D Sex and Zen: Extreme Ecstasy is a 2011 Hong Kong 3D erotic costume drama film directed by Christopher Suen and produced by Stephen Shiu. It was released in Hong Kong, South Korea, Australia and New Zealand on 14 April 2011. It is a new instalment of the Sex and Zen series and is loosely based on the 17th century Chinese novel The Carnal Prayer Mat. As compared to the original film series, it is more dark and dramatic, and it occasionally pays homage to the humour of the earlier films.
