Lucia Murat, a veteran documentary maker in Brazil, tells the story of her younger brother, Heitor, who was sent to London by his parents in the late 60s so he wouldn't get mixed up in revolutionary politics like his sister. Instead, he spent a decade bopping around the world (Athens, Sydney, Kabul, Rishikesh, New York) and trying every drug he could get his hands on, until eventually he was diagnosed as schizophrenic. Murat draws heavily on letters Heitor wrote back in the day, which detail his wanderings but lack the self-knowledge necessary to transform this prosaic family memoir into the poetic evocation of the Vietnam generation that she clearly intends it to be. An aging and rather dissipated Heitor sits for extensive interviews, which do little to dispel the sense of a leisure-class kid's decade of self-indulgence being repackaged as a spiritual quest. In Portuguese with subtitles.
