Talking about dreams is like talking about movies, since the cinema uses the language of dreams; years can pass in a second, and you can hop from one place to another. It's a language made of image. And in the real cinema, every object and every light means something, as in a dream.
In 'Roma,' I wanted to get across the idea that underneath Rome today is ancient Rome. So close. I am always conscious of that, and it thrills me. Imagine being in a traffic jam at the Coliseum! Rome is the most wonderful movie set in the world... As was the case with many of my film ideas, it was inspired by a dream.
