Guerra y Paz, primera parte | BASADA EN LA NOVELA DE LEÓN TOLSTÓI

Sergei Bondarchuk opens his adaptation of Tolstoy with Russian society drifting toward war with Napoleon, following Andrei Bolkonsky, Natasha Rostova and Pierre Bezukhov from ballrooms to the field at Austerlitz. The scale, built with thousands of Soviet Army extras, is still close to unmatched.
