[Role of Dr.Strange] gives me an excuse as an actor to be learning with my character, which is something you can do authentically - I'm not a martial arts expert, I'm certainly no sorcerer, so all these things, the movement of the body, the physicality, the changes he goes through mentally and physically, obviously we're not shooting in sequence, but it's a great part.

If you have an over-preoccupation with perception and trying to please people's expectations, then you can go mad.

Doctor Strange is selfish but he's still saving lives.

Scott Derrickson breathes humour into a character with a very strong identity in the '60s and '70s, that psychedelia era of Eastern mysticism meeting the West.

I've never done a lead role in a film this big [like Doctor Strange], in a franchise this big. One of the reasons was, I wanted to know what the toy box was like. And it's just insane, the amount of facility that everyone gets, but the amount of artistry and craft that's brought to every aspect of filmmaking. I mean, you go to your first costume fitting and it's one of thirty. It's a myriad, but it's for a reason. There are so many incredible costumes in this.

Marvel always make it fresh so you can give it your personal twist.

There's another weight of us being in the public eye, which is this presumption that, because your work and your promotion work is very public, your private life should be, too.
