Twice a year in Cambodia, the Tonle Sap River changes course, while life for the Cambodian people continues to flow in a perpetual cycle of death and rebirth and of creation and destruction. Working in an intimate, verité style, filmmaker Kalyanee Mam (Director of Photography for the Oscar-winning documentary Inside Job), spent two years in her native homeland following three young Cambodians as they struggled to overcome the crushing effects of deforestation, overfishing, and overwhelming debt. A breathtaking and unprecedented journey from the remote, mountainous jungles and floating cities of the Cambodian countryside to the bustling garment factories of modern Phnom Penh, A River Changes Coursetraces a devastating and beautiful story of an ancient culture ravaged by globalization. Directed by Kalyanee Mam.
