Now, a 3D porn film — the world’s first — has taken it down. 3D Sex and Zen: Extreme Ecstasy opened in Hong Kong with ticket sales totaling HK$2.8 million, reports. The film’s total gross so far hovers around HK$15 million ($1.9 million U.S.). Demand is so high that an extended version of the movie has been announced for release in a few weeks, adding an additional 15 minutes to the running time.
