LOS ANGELES - Vivid Entertainment will release Throat: A Cautionary Tale this Wednesday, March 25.

Directed by Paul Thomas, the "porn noir" feature starring Sasha Grey is the subject of World of Wonder's reality series "Deeper Throat". It is also the subject of a lawsuit filed by Arrow Productions owner Ray Pistol, who claims Vivid has violated his rights to the famous title Deep Throat.

Now airing on Showtime, "Deeper Throat" shows the Vivid camp clashing with Pistol and company during production of the movie.

Throat: A Cautionary Tale earned a perfect 5A rating from AVN.

"Some fans may find the movie a downer, but folks who crave compelling drama with their hardcore sex need look no further," wrote veteran critic Jared Rutter. "This is adult feature filmmaking at its best."
