He is known especially for a trilogy of war films: A Generation (1954), Kanał (1956) and Ashes and Diamonds (1958).

Four of his films have been nominated for the Academy Award for Best Foreign Language Film: The Promised Land (1975),The Maids of Wilko (1979), Man of Iron (1981), and Katyń (2007).

Wajda' father was murdered by the Soviets in 1940 in what came to be known as the Katyn massacre. In 1942 he joined the Polish resistance and served in the Armia Krajowa. After the war, he studied to be a painter at Kraków's Academy of Fine Arts before entering the Łódź Film School.
