Smoktunovsky was born in a Siberian village in a peasant family of Belarusian ethnicity. It was once rumored that he came from a Polish family, even nobility, but the actor himself disapproved those theories by stating his family was Belarusian and not of nobility. He served in the Red Army during World War II. In 1946, he joined a theatre in Krasnoyarsk, later moving to Moscow. In 1957, he was invited by Georgy Tovstonogov to join the Bolshoi Drama Theatre of Leningrad, where he stunned the public with his dramatic interpretation of Prince Myshkin in Dostoevsky's The Idiot. One of his best roles was the title role in Aleksey Konstantinovich Tolstoy's Tsar Fyodor Ioannovich (Maly Theatre, 1973).
