Director Krzysztof Zanussi's collaboration with Wojciech Kilar was a worldwide phenomenon. The artists' paths had already converged in the 1960s, and were not to part until Kilar's death. The composer wrote music to the young filmmaker's debut picture Struktura kryształu / The Structure of Crystals (1969), and Zanussi was so impressed with both the soundtrack and Kilar's understanding and general savvy that he kept submitting his artistic proposals only to him. As a result this outstanding duo completed over forty feature films, as well as documentaries and television works. In a short story by Krzysztof Zanussi we learn more about this unique, long-term cooperation.
