Samson (1961 Polish film): Samson is a 1961 Polish film directed by Andrzej Wajda that uses art house aesthetics to tell a story about the Holocaust.  Wajda's World War II film alludes to the Old Testament story of Samson, who had supernatural physical strength.  But unlike the Biblical character, Wajda's Samson has great emotional strength.

Andrzej Korzyński: Andrzej Korzyński is a Polish composer who has worked with film directors Andrzej Wajda ("The Birch Wood", "Man of Marble") and Andrzej Żuławski.

Craig Melville: Craig James Melville is an Australian television comedy director.  He is best known for his collaborations with comedians John Safran, Lawrence Leung and The Chaser.

Andrzej Wajda: Andrzej Witold Wajda (] ; 6 March 1926 – 9 October 2016) was a Polish film and theatre director.  Recipient of an Honorary Oscar, the Palme d'Or, as well as Honorary Golden Lion and Golden Bear Awards, he was a prominent member of the "Polish Film School".  He was known especially for his trilogy of war films consisting of "A Generation" (1954), "Kanał" (1956) and "Ashes and Diamonds" (1958).

A Generation: A Generation (Polish: Pokolenie ) is a 1955 Polish film directed by Andrzej Wajda.  It is based on the novel "Pokolenie" by Bohdan Czeszko, who also wrote the script.  It was Wajda's first film and the opening installment of what became his Three War Films trilogy set in the Second World War, completed by "Kanal" and "Ashes and Diamonds".

Theatre of Poland: In common with other European countries, the most frequent and most popular form of theatre in Poland is dramatic theatre, based on the existence of relatively stable artistic companies.  It is above all a theatre of directors, who decide on the form of its productions and the appearance of individual scenes.  There is no strict division in Poland between theatre and film directors and actors, therefore many stage artists are known to theatre goers from films of Andrzej Wajda, for example: Wojciech Pszoniak, Daniel Olbrychski, Krystyna Janda, Jerzy Radziwiłowicz, and from films of Krzysztof Kieślowski, actors such as Jerzy Stuhr, Janusz Gajos and others.

Man of Marble: Man of Marble (Polish: "Człowiek z marmuru" ) is a 1976 Polish film directed by Andrzej Wajda.  It chronicles the fall from grace of a fictional heroic Polish bricklayer, Mateusz Birkut (played by Jerzy Radziwiłowicz), who became the Stakhanovite symbol of an over-achieving worker, in Nowa Huta, a new (real life) socialist city near Kraków.  Agnieszka, played by Krystyna Janda in her first role, is a young filmmaker who is making her diploma film (a student graduation requirement) on Birkut, whose whereabouts seems to have been lost two decades later.  The title refers to the propagandist marble statues made in Birkut's image.  It is somewhat of a surprise that Wajda would have been able to make such a film, "sub silentio" attacking the socialist realism of Nowa Huta, revealing the use of propaganda and political corruption during the period of Stalinism.  The film director presaged the loosening grip of the Soviets that came with the Solidarity Movement, though it has been acknowledged by Polish film historians that due to censorship the script languished in development hell since 1962.  The film extensively uses original documentation footage from the construction of Nowa Huta and other subjects of Poland's early communist era, as well as the propagandist/inspirational music of Stalinist Poland.

Afterimage (film): Afterimage (Polish: Powidoki ) is a 2016 Polish drama film directed by Andrzej Wajda.  It was screened in the Masters section at the 2016 Toronto International Film Festival.  It was selected as the Polish entry for the Best Foreign Language Film at the 89th Academy Awards but it was not nominated.  It is the final film by Wajda who died in October 2016.
