Desc: When Hippies Ruled the World: Directed by Andy Baybutt. With Kathy Burke, Joni Mitchell, Dennis Hopper, Rosie Boycott. As seen through the blurred eyesight of the coolest cats of the sixties, this documentary takes a trip back to the end of the psychedelic Sixties - the dreams, trips, movies, and music - to a time when love was all that was needed.
