I think that film festivals, we're very often given to understand, are about filmmakers and about films and about the industry of filmmaking. I don't believe that they are, I believe that film festivals are about film audiences, and about giving an audience the encouragement to feel really empowered and to stretch the elastic of their taste.

It's exotic for me to be given a script that's already written, and be given a pay cheque, and asked to dress up and play, and that's all.

The Ancient One, as you know, is the master, is the Sorcerer Supreme, and [Doctor] Strange comes to learn how to heal himself and The Ancient One has got the knowledge. And so what you're seeing today is a part of the whole training section when he's learning the moves and digging deep. So it's all about that, it's all about trying to push him to get there.

One of the things about Derek Jarman was that he was a painter who worked alone when he painted, but I firmly believe that one of the reasons he made films was for the company. He made filmmakers of all of us, that's the truth. I don't mean he necessarily made directors, but he made us filmmakers. Because we lived in a state of mutual responsibility for what we made.

The story, it's really important to The Ancient One that Doctor Strange does cut it because The Ancient One needs a successor, or certainly needs - you could say - a son. So The Ancient One is really invested in Doctor Strange, it's a very kind of primal relationship.

What children, in fact all of us at any age, find frightening is unreliability and emotional coldness. The idea that you can't affect someone, that you can't see where they're coming from and can change tact at any moment.

I've been really happy to be in that conversation with Scott [Derrickson] for a few months now. We started chewing this cud a while ago. He is, as you probably know, an extremely erudite thinker in terms of religious philosophy and just thinking about a modern take on something really, really ancient, about how to imagine living beyond any physical bounds, which we're on the verge of now.
