Krzysztof Kieślowski said this quote
“ Or take this girl, for example. At a meeting just outside Paris, a fifteen-year-old girl came up to me and said that she'd been to see [The Double Life of] Véronique. She'd gone once, twice, three times and only wanted to say one thing really - that she realized that there is such a thing as a soul. She hadn't known before, but now she knew that the soul does exist. There's something very beautiful in that. It was worth making Véronique for that girl. It was worth working for a year, sacrificing all that money, energy, time, patience, torturing yourself, killing yourself, taking thousands of decisions, so that one young girl in Paris should realize that there is such a thing as a soul. It's worth it. ”
