American Grindhouse (2010), Elijah Drenner.

American Grindhouse is Exploitation Films 101: a good overview of movies that fall outside the realm of good taste, movies that were generally excluded from the mainstream viewing experience.  It explores the evolution of the genre from the first moments of nudity caught on film, to the educational sex pictures, to women-in-prison movies, to gore and eventually porn.  American Grindhouse posits that there's often been a great, productive relationship between the taboo and the mainstream and at times often not much difference between the methods of an exploitation film dismissed as trash (Blood Feast, Last House on the Left) and methods used by directors who couldn't be more revered (Psycho's Hitchcock, Jaws's Spielberg).

John Landis, one of the interviewees, is delightfully entertaining to listen to as is Kim Morgan, film writer and author of Sunset Gun blog:  http://sunsetgun.typepad.com.  In Sunset Gun she appears fully immersed in the long lost world of the Hollywood golden era, speaking intimately of stylish, long gone film icons.  I would suggest she may even be depicting herself as a character who could have walked out of a film noir:  sexy L.A. blonde with a taste for classic cars.  I got a big kick out of Morgan because in American Grindhouse she's surprisingly funny.  Big noir thinker Eddie Muller also appears and many of the ideas he expressed in his 1996 book Grindhouse: The Forbidden World of "Adults Only" Cinema gives American Grindhouse its intellectual backbone.  Hey, don't skip over this - picking through trash can be quite revealing.
