"Mau Mau Sex Sex" is an excellent documentary about Dan Sonney and David F.Friedman who made exploitation movies.Sonney and Friedman teamed up on countless nudies-nudist camp movies that were ultimate in sex movies in 1960's.Later they started making roughies like "The Defilers".The splatter classic "Blood Feast" is also presented here with its memorable tongue ripping scene but curiously without any credit given to director Herschell Gordon Lewis.A must-see if you're into exploitation cinema!
