As part of the major heritage interview program conducted in 2006 by the French National Audiovisual Institute (INA) in collaboration with the Foundation for the Memory of the Shoah, Roman Polanski recorded his account of his childhood in Poland during the war. It was while writing that he remembered asking his father, in 1973, to write his memoirs. He recently rediscovered his father's account, which he had never read before. It now forms the second part of this unique book, Letters to My Son by Ryszard Polanski, bringing together a father and son in two moving and enlightening testimonies of historical memory.
