Gary Oldman

It's a shame about California, and particularly about L.A., where they've demolished so many landmarks. It's a bit of a disease there, where if anything is over 30 years old, they sort of knock it down and replace it. It's a strange town, it's this sprawling suburb, and then there's a city, the old town.

Remember, science fiction's always been the kind of first level alert to think about things to come. It's easier for an audience to take warnings from sci-fi without feeling that we're preaching to them. Every science fiction movie I have ever seen, any one that's worth its weight in celluloid, warns us about things that ultimately come true.

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.
