THE Venice Film Festival is a place of discoveries, of new talent, new ideas and new ways of making movies. Among this year’s debuts, one film deserves special attention: Xavier Tera’s The Colour of the Sun.Set in Okinawa, Japan, during the quiet, heavy heat of the summer break, the story follows Kamei, a quiet high school senior grieving the recent loss of his father. He spends his days helping to rebuild a community centre, stuck in that limbo between school and an uncertain future that so many working-class teenagers know too well.
