From Wikipedia
Jerzy Kawalerowicz (19 January 1922 – 27 December 2007) was a Polish film director and politician, having been a member of Polish United Workers' Party from 1954 until its dissolution in 1990 and a deputy in Polish parliament since 1985 until 1989.
Jerzy Kawalerowicz was noted for his powerful, detail-oriented imagery and the depth of ideas in his films. After working as an assistant director, he made his directorial debut with the 1951 film The Village Mill (Gromada). He was a leading figure in the Polish Film School, and his films Shadow (Cień, 1956) and Night Train (Pociąg, 1959) constitute some of that movement's best work.
