A new film set in a French chateau - and starring the real Chateau Clos Fourtet - opens next month in French cinemas. Tu Seras Mon Fils (You Will Be My Son) deals with the conflict between a fictitious chateau owner and his son. It was almost entirely filmed at the Saint Emilion Premier Grand Cru Classé Chateau Clos Fourtet, and features the chateau’s actual staff as well as established French stars, from director Gilles Legrand to actors Niels Arestrup - who is in Stephen Spielberg's forthcoming film War Horse, Anne Marivin (Little White Lies), Patrick Chesnais (The Diving Bell and the Butterfly) and Lorànt Deutsch.
