Quentin Tarantino might want to study skin flicks a little harder before he penetrates the porn industry. Fresh off his bomb Grindhouse, Tarantino has been toying with the idea of making 3D porn.

The Pulp Fiction director says 3D porn would be "the perfect next step for the adult genre." Furthermore, he tells Total Film magazine, "Right now it's still in my mind. But I've been musing at what I would do if I could make a 3D porn film! It hasn't been green-lit yet, as I still have a few things to work out on it!"

Quentin, we're sorry to say this, but you're a tad too late.

The 3D porn idea has not only already been green-lit, but it's already been produced. Producer/director Bobby Rinaldi of Wild Life Productions [NSFW] recently released another installment of the best-selling series Screw My Wife Please..., and it's in 3D. The flick, hosted by veteran Dave Cummings, pairs a male porn star with a married woman while her husband watches the steamy action unfold in front of him. It is set for release at the end of September.

The three-DVD set comes with 3D glasses that bring each money shot astonishing new life.

"Tarantino has a great idea, but I came up and have done it first," Rinaldi tells Radar. Asked if he would consider collaborating with Tarantino for Wild Life's next 3D project, Rinaldi flat out said no, citing the confidentiality of the technology. "Only my guy has the knowledge and equipment," he says.
