Milos Forman

Because his parents died in the Nazi concentration camp of Auschwitz, Milos Forman became an orphan very early on. Later, he studied direction at the School of Cinema in Prague. In his Czechoslovakian films, Cerny Petr/Black Peter, Lasky Jedne Plavovlasky/Loves Of A Blonde, and Hori, Ma Panenko/The Firemens Ball, he created his own style of comedy. During the invasion of his country by the troops of the Warsaw pact in the summer of 1968 to stop the Prague spring, he left Europe for the United States. In spite of difficulties, he achieved fame with One Flew Over The Cuckoos Nest, adapted from the Ken Kesey novel, which won five Oscars including best director.

Hori, Ma Panenko/The Firemens Ball - 1967
A milestone of the Czech New Wave, Milos Formans first color film The Firemens Ball is both a dazzling comedy and a provocative political satire. A hilarious saga of good intentions confounded, the story chronicles a firemen’s ball where nothing goes right—from a beauty pageant whose reluctant participants embarrass the organizers to a lottery from which nearly all the prizes are pilfered. Presumed to be a commentary on the floundering Czech leadership, the film was “banned forever” in Czechoslovakia following the Russian invasion and prompted Forman’s move to America.
