As quoted in "Kieślowski's Many Colours" by Patrick Abrahamsson, in Oxford University Student newspaper (2 June 1995)
Context: I don't make biographical films … None of the films is about me. Not a single one. None. I have my life and I'll simply never tell anyone what part of me is in my films. I won't ever tell anyone about that, because I don't consider that to be anyone else's business but mine. Nobody will guess where and how and in what way I fill them with my own pains. And that's an intimate aspect of my work that I keep to myself. … I won't even tell my wife — ever.
