«I think one of the biggest problems that we have in our business is the inability of people to visualize. Imagine a composer sitting down with a blank music sheet in front of him, and a full orchestra. ‘Flute, give me a note if you please. Yes, thank you very much,’ and he writes down. It’s the same thing, but a man can compose music directly on paper and what’s the result? It comes out a gorgeous sound. The visual, to me, is a vital element in this work. I don’t think it is studied enough.»
Alfred Hitchcock, Directing the film.
Alfred Hitchcock fue Director de Arte antes que Director, y cuidaba mucho el acabado de los sets. Tanto que siempre que podía supervisaba directamente a Robert F. Boyle, uno de sus Diseñadores de Producción fetiches.
