When you actually see it, it is quite strong, but there's nothing really pornographic about it. They are high-impact yet very short moments of sexuality, which makes it very confusing for the censors. If censors were merely human beings who watch a film ["Aquarius"] and come out with a conclusion about what they saw, then there wouldn't be a problem.

Nobody who comes out of the movie [Aquarius] focuses on those [sexual] scenes, because they are not the heart of the film. They are a consequence of the story, but I don't remember hearing audiences talking about them afterward. They came out discussing themes of resistance, history and memory. They're talking about the beauty of the self and how it can become demolished.

People have reacted to the length of "Aquarius" in very positive ways. For example, at the beginning, you have people in a car on the beach at night. One character says, "I'm going to play you this great track." She pushes in a cassette tape, and they listen to about 45 seconds of Queen's "Another One Bites the Dust." You can actually see the pleasure registering on their faces, but it takes time, and audiences have appreciated that.

The ruins of classic movie theaters are a personal obsession of mine, and I've made a couple of documentaries about it.

And getting older, what's happening is, I play only mothers.

I have two kids now and through watching them, I keep having flashbacks to my own childhood.

Ultimately, you just have to do what feels right for the film. It really helps when you have great collaborators like my editor, Eduardo Serrano, who kept telling me various scenes should be longer.
