Anna Marie de la Fuente In a new deal secured at this week’s San Sebastian Festival, Birgit Kemner’s Manny Films has partnered with Chile’s Storyboard Media to co-produce “Un Buen Día Para Morir” (“A Good Day to Die”), the third feature by Marcelo Ferrari (“Subterra,” “Bombal”). Inspired by the real story of pianist María Paz Santibáñez whose life took a dramatic turn during a protest against General Pinochet’s dictatorship in 1987, the drama turns on 24-year-old piano student Pachi who is shot in the head during a protest against the military regime. Seriously injured and pregnant, she manages to survive and give birth to her daughter. Escaping Chile, she settles in Paris where – against all odds – she fulfills her dream to become a concert pianist.
