Maciej Drygas  Maciej Drygas (born 1956 in Łódź) is a Polish documentary filmmaker. Following graduation from the Directing Department of the Moscow All-Russian State Institute of Cinematography (VGIK), also known as the Gerasimov Institute of Cinematography, he worked as an assistant to Krzysztof Zanussi and Krzysztof Kieślowski. His first documentary as director was "Hear My Cry", about Ryszard Siwiec, who, in September 1968, protested against communist totalitarianism, and in particular the entry of Warsaw Pact forces into Czechoslovakia, by setting fire to himself (self-immolation) in front of thousands of people during the harvest festival at the 10th Anniversary Stadium in Warsaw, an incident that was censored in the media at the time. His follow-up film, Weightless, looks at the human cost of the Russian space programme. Drygas is currently director of the radio drama section at the Reportage Laboratory at Warsaw University and also teaches regularly at the Łódź Film School.
