"I'm in love with the flickering muse, and I share the fate of many men in love: I love her not as she is, but as I would like her to be. For I believe in art in the cinema. But I doubt whether a work of cinematic art has so far ever been made. You can't cure a sick man by painting his cheeks in fresh colors. And you can't turn a film into a work of art by augmenting it and exalting it with "quality". You can gather together the best mimes in the world, you can let them perform in the most exquisite paradise, you can adorn the programs of your film dramas with the names of the most eminent poets - art will never result that way. A work of art will result only if it is born of the possibilities and demands of its material." (Walter Ruttmann, in R Bruce Elder, Harmony and Dissent: Film and Avant-Garde Art Movements in the Early 20th Century, p117)
