"When I do a film that has nothing to do with Kurt Weill, then I am happy, I am on my own. But in a Kurt Weill work I am as nervous as a cat. A burden falls on my shoulders. I feel a crushing responsibility."

(Lotte Lenya, pseudonimo di Karoline Wilhelmine Charlotte Blamauer, attrice e cantante; Vienna, 18 ottobre 1898 – New York, 27 novembre 1981)
