Today on the Inside Deep Throat blog, the former happy hooker Xaviera Hollander and uberplayboy Hugh Hefner remember their first times with Deep Throat.

And there’s more press. Mark Caro in the Chicago Tribune called the WOW doc “the most buzzed-about premiere of the Sundance Film Festival’s opening weekend.” We knew that.

“Inside Deep Throat,” which Universal is releasing next month, is part “Kinsey” (its view of the nation’s former state of sexual repression), part “The People Vs. Larry Flynt” (the recounting of censorship/First Amendment battles, culminating in the criminal trial of leading man Harry Reems) and part “Boogie Nights” (immersion in the pre-video porn world, all set to a fab ’70s soundtrack that includes “Spill the Wine”). With its graphic movie clips and the subject’s frank treatment, “Inside Deep Throat” will become that very rare species: a major-studio NC-17 film (Universal’s first since 1990’s “Henry & June”).
