KEEP THE RIVER ON YOUR RIGHT: A MODERN CANNIBAL TALE (2002)

Sitting atop Machu Picchu nearly half a century after he disappeared into the Amazonian forest of Peru and befriended a cannibalistic tribe, Tobias Schneebaum bites into a passion fruit with obvious delight. The moment would be wink-wink ironic if ''River'' stopped at sensational rehash (omigod, this guy ate people!). Rather, the film, which follows the anthropologist as he revisits the tribe, winds up being a meditation on the ageless search for what Schneebaum can ultimately only call ''inner peace.''
