"Enjoying an old port wine together, I was talking with Manoël about the bridges of Douro, and immediately we were of the same opinion: of all these bridges, the great work of art in the capital of modern architecture is the bridge that Gustave Eiffel had done before building his tower of Paris. In less than five minutes, the project was constructed: Manoël was writing a poem that we will film with our friends Bernard, Jérôme, and François. And our dreams of childhood were made in less than a week by going back and forth to the banks of Douro, on foot, then by car, then in a helicopter, back to where we were following these marvelous clouds, with Manoël and me screaming stanzas of a poem inspired by the wind, the water, and friendship." - Jean Rouch
