I just saw the emotion in everything, so I got to feel everything that was going on and that I was viewing, but I couldn't think in terms of structure, which is the whole point of deep focus.
I studied Hitchcock a little bit at University and knew the famous story about the Birds - that he'd tortured Tippi for a day using real birds. I had no idea that it was a five-day onslaught and that it was the tip of an iceberg that carried on through to another film.
No one ever attains success by simply doing what is required of him.
