Walerian Borowczyk (September 2, 1923 – February 3, 2006) was a Polish film director. He directed 40 films between 1946 and 1988. His career as a film director was mainly in France.
Born in Kwilcz, he studied painting at the Academy of Fine Arts in Kraków, then devoted himself to painting and lithography, including the creation of posters for the cinema, which earned him a national prize in 1953. In 1959, he settled in Paris.
His early films were surreal animations, some only a few seconds long, including several comic abecedaria (letter lists). His most acclaimed early films were Był sobie raz (Time Upon a Once) (1957) and Dom (House) (1958, with Jan Lenica).
His influence can be seen in the work of Jan Svankmajer and The Quay Brother:
