Michael Gambon

There's no subtext in 'Harry Potter,' really; it's all magic - anything can happen. Why do I say this? Because it's a magic spell. It's quite nice in a way. There is a real freedom to it. Doesn't say much for acting, does it?

I sometimes think the theatre is more demanding because it requires things you don't have in films, like it requires you to make the people in the front row believe you and not look an idiot to them while the people right at the back can hear you.

It is only when you watch the dense mass of thousands of ants, crowded together around the Hill, blackening the ground, that you begin to see the whole beast, and now you observe it thinking, planning, calculating. It is an intelligence, a kind of live computer, with crawling bits for its wits.
