There were a lot of bad documentary films about teens and drugs in the late 60s and early 70s. Many are laughable. While there are elements to this in "A Movable Scene", it stands up a tad better than most over time.
The film chooses a VERY interesting and surprising narrator, Robert Mitchum. While many folks today don't realize it, this famous actor has an infamous blot on his Hollywood image...he was arrested for pot use and sent to jail while he was on his ascent in films. Oddly for the time, in some ways the incident seemed to help his career...giving him a bad-boy image. Here in the film, he seems like a dubious guy to be giving us advice about the hippie culture and drugs...especially when the film seems to condemn drugs! I think it would have been MUCH more effective had Mitchum talked about his experiences with drugs and explain why he thought they were bad...especially since you wonder if he really did!
The documentary is about the hippie culture but instead of demonizing ALL of it, it seems to say that the drug abuse is not good BUT adults have a responsibility in it. They need to talk to teens about why they are disaffected with society and help channel this energy into helping others and bettering the world instead of selfishly tuning out with drugs. Not a bad message...hence my giving it a 5. An odd curio, that's for sure and an unusual film for Turner Classic Movies to show.
