Emerald fields of cannabis plants—and smoking petrochemical plants. A bearded Californian lifting trays of hemp paper—and an Australian eucalyptus forest decimated for wood pulp. An elderly Nepalese grinning as he exhales a plume of black-hash smoke—and armed narcs kicking in doors while Drug Warriors from Harry Anslinger to George Bush proclaim imminent victory. These are the images at war in The Hemp Revolution, an ambitious low budget documentary that aspires to be the celluloid equivalent of Jack Herer’s The Emperor Wears No Clothes. This is a very informative and enjoyable movie.
