Hippie exploitation films
Hippie exploitation films are late 1960s-early-to-late 1970s exploitation films about the hippie counterculture with situations associated with the movement such as marijuana and LSD use, sex and wild psychedelic parties. == Overview == From almost the beginning, Hollywood and independent studios got in on the action and produced a number of extremely lurid hippie exploitation (and/or hippie horror) films that were either supporting the subversive playful artistic side of the culture war, or masquerading as cautionary public service announcements, but which were in fact aimed directly at feeding a morbid public appetite while pretending to take a moral stance.
