Baz Luhrmann

Opera was the cinema of its time, so to bring back that popular appeal, you just need to unleash its visceral immediacy and excitement. Most productions don't manage that - but when an opera does do it, you never forget it.

Sometimes you see films, not just science fiction films, where you get the sense that if the camera were to pan just to the left or the right, all of a sudden you'd be seeing light stands and crew standing around. But with 'Blade Runner,' the beauty of it is that it felt like a real, breathing city.

Noises and smells, those can bring back powerful memories. I remember when I was going to school one Fourth of July, and there were a lot of fireworks going off. I knew that I was in Richmond. I knew that I was a college student. But I thought people were shooting at me.
