I'm Glad My Mother Is Alive (2009)

Based on a true story, critically acclaimed French filmmaker Claude Miller and his son Nathan Miller explore childhood trauma and its consequences on adult life. Given up for adoption as a toddler, troubled teenager Thomas becomes obsessed with tracking down his birth mother. After years of searching Thomas finds her single, with a small child, living in a nearby suburb and introduces himself. Traumatized by years of emptiness and longing for his mother, he starts an ambiguous relationship with her (part courtship, part obsession) which slowly drives him to an act of madness. With striking performances and a shocking twist, 'I'm Glad My Mother Is Alive' is hard to get out of your mind.
