In yet another sign that the United States is losing its edge in the world, China is where you have to go to see what is being billed as the world’s first 3D porn film. Well, it’s perhaps at least the world’s first 3D IMAX porn film—yes, we know you folks with the fancy-schmancy home theater setups are already doing your extra-dimensional thing, but that’s not IMAX, with 60-foot-tall dudes and chicks and such. Sex and Zen: Extreme Ecstasy is apparently not like anything seen these days on the biggest screens in America; it’s a movie so salacious that Chinese audiences are reportedly flocking from the mainland to more permissive Hong Kong for the chance to see an uncut version.

Writer and producer Stephen Shiu says the film would feature some “very graphic sex scenes,” adding, “It will leave audiences feeling like they are sitting right there at the edge of the bed.” The movie is based on a classic Chinese erotic story called The Carnal Prayer Mat, the tale of a man who meets a duke who introduces him to a world of luxurious orgies.

But ... and we know you're thinking this ... Is the world really ready for IMAX 3D penises?

We’re kind of not expecting Sex and Zen at our local multiplex so if you happen to catch it, let us know if it’s any good, okay? All we’ve got is this trailer to go by.
