Polish filmmaker Jerzy Kawalerowicz was once considered one of his country's most talented post-WW II directors, noted for his powerful, detail-oriented imagery. Kawalerowicz was versatile and his subjects ranged from historical dramas to intense psychological studies. He made his directorial debut in 1951 after working as an assistant director. In 1955 Kawalerowicz was appointed head of the prestigious KADR production unit. He held the position again in 1972. In 1983, Kawalerowicz alienated himself from many of his peers by signing communist government-generated reports condemning all filmmakers aligned with the Solidarity Movement and promoting the destruction of production units run by long time associates Wajda and Zanussi. Kawalerowicz died in December 2007, about a month before his 86th birthday.
