James Franco has released a new trailer for Kink, his documentary exploring the world of BDSM and fetishes.

Franco and director Christina Voros visited the studios of Kink.com, one of the Web's biggest purveyors of kinky porn, to demystify BDSM and explore why people, both straight and gay, are drawn to it.

Kink made its debut at Sundance, and will have a limited release in the U.S. starting August 22.

It's not Franco's first time at the kinky rodeo—he co-created 2013′s Interior. Leather Bar, which was inspired by x-rated scenes reportedly cut from the movie Cruising.
