On Mars in the year 2045, a filmmaker sends messages to his father that reflecting on footage he made years ago of Vietnam’s Cor and Rục peoples, including an extended interview with a man who spent forty years living in a tree house after American forces bombed his home during the Vietnam War. In Truong Minh Quý’s ambitious science fiction/documentary/essay film hybrid, the documentary footage is real. It juxtaposes Truong’s own sympathetic portrayal of these indigenous people with shocking footage shot by American soldiers as they laid waste to their villages. Situating it in a science fiction frame tale about a future colonized Mars allows him to create a brilliant, unsettling consideration of memory, the ethics of documentary image-making, and the nature of home.
