Younger son of the director and Larissa Pavlovna, Andrei Andreievich is the chairman of the Florence- and Paris- based Andrei Tarkovsky International Institute, which safeguards the legacy and testimony of the Russian filmmaker. His relationship with his father was marked by a five-year period of separation due to the Soviet authorities' refusal to grant him the necessary permit to leave Moscow to join his parents, in self- imposed exile in Europe. During this separation and already with terminal cancer, Andrei Tarkovsky dedicated his last film, The Sacrifice, to Andriusha, as a declaration of his hope and faith in the future. The USSR finally gave Andriusha the visa he needed and he was able to visit his father in hospital shortly before his death. Their embrace marks the beginning of Chris Marker's One day in the life of Andrei Arsenevich."
