Porn Valley- One of the most culturally significant and successful films of all time, 1972’s Deep Throat, is now the subject of a-what else?-sexually graphic documentary feature. Inside Deep Throat, www.xxxdeepthroat.com, directed by Party Monster’s Fenton Bailey and Randy Barbato and produced by A Beautiful Mind’s Brian Grazer, will explore how a little porn film with a provocative title ended up being a big, big touchstone of ’70s cinema.

Universal Pictures is releasing the doc, which features interviews with playboys of the era like Jack Nicholson, Norman Mailer, Warren Beatty, and Hugh Hefner, as well as gay cultural icons John Waters and Gore Vidal. Look for the unrated film to hit theaters in 2005.
