Billy Ocean

And you realise you're doing a public service in making people happy - as a musician you can give people something a doctor, a lawyer, a politician cannot give them that. It's not scientific. It's spiritual - a good feeling. And although you don't know them personally, the audience are like your friends.

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.
