"About a year ago, Krzystof Kieslowski recieved a courteous letter from Oxford University Press. They were in the process of updating their music encyclopaedia, and could he please provide them with some details about Van den Budenmayer, the late 18th century Dutch composer whose music he had featured in his Dekalog, Double Life of Veronique and Three Colours trilogy. Their research had yielded nothing. Kieslowski replied equally courteously that Van den Budenmayer was a fictional character created by him and his composer, Zbigniew Preisner. Soon he received a second letter. Of course they understood his concern to protect his sources, but as this was to be the definitive series on classical music could he please provide them with at least some information. Kieslowski wrote a second letter, reiterating that the score had been written by Preisner, a 19 stone self-taught musician from Cracow. Still they did not believe him. After about half a year of this fruitless correspondence back and forth Kieslowski stopped replying."
