The script is simply a series of notes for the film.

A woman's sex appeal is an inner matter. It stems from her mental make-up, basically. It's an attitude, not just a question of her physical features - that arrogant quality in a woman's femininity. Otherwise, all beautiful women would have sex appeal, which is not so.

Take Einstein; wasn't he looking for something stable and changeless in this enormous, constantly changing melting pot that is the universe? He sought fixed rules. Today, instead, it would be helpful to find all those rules that show how and why the universe is not fixed - how this dynamism develops and acts. Then maybe we will be able to explain many things, perhaps even art, because the old instruments of judgment, the old aesthetics, are no longer of any use to us - so much so that we no longer know what's beautiful and what isn't.

The photographer in Blow-Up, who is not a philosopher, wants to see things closer up. But it so happens that, by enlarging too far, the object itself decomposes and disappears. Hence there's a moment in which we grasp reality, but then the moment passes. This was in part the meaning of Blow-Up.

Neorealism taught us to follow the characters with the camera, allowing each shot its own real interior time. Well, I became tired of all this; I could no longer stand real time. In order to function, a shot must show only what is useful.

I forget about the relationship between myself and any actress when working with her.

A particular type of film emerged from World War Two, with the Italian neorealist school. It was perfectly right for its time, which was as exceptional as the reality around us. Our major interest focused on that and on how we could relate to it. Later, when the situation normalized and post-war life returned to what it had been in peacetime, it became important to see the intimate, interior consequences of all that had happened.
