[Doctor Strange] is still quite cocky by the end of the film. No, I'd say the major curve for him is that he learns that it's not all about him, that there's a greater good. But what he thinks he was doing as a neurosurgeon, that was good because it benefitted people's health was really just a furtherment of his attempts to control death and control his own fate and other people's, but that's still driven by the ego.

Doctors and nurses do crazy hours and keep an ideal afloat through the love and care that they have for their craft and their patients and the institution of the NHS. We should be very proud of it.

[Scott Derrickson] is terrific, really sharp on the details, and he's not afraid to go to dark places.

I keep myself amused and others confused

That's something I have to work on: to separate what really matters, to conserve energy by not worrying about what other people think. When I walk through that door, it's about home. If I didn't do that, I'd become consumed by one thing only and damage the people who love me. And it would damage the work.

I've been quite a late developer on the clothes front, but I've suddenly realised it is one of life's joys.

I always get self-conscious about what I look like in a film, but less so if I'm a character very far removed from who I am. Then I just worry about the performance, and that's equally an odd experience.
