Only when Stephen Strange has his accident and everything that he's ever had in his life falls apart that he becomes pretty monstrous. It's the self-loathing rage of a wounded animal and he doesn't have a coping mechanism at all. It ties in with the discipline and the magic of this world.

I don't live beyond my means. I enjoy luxury and I enjoy the privilege of it, when I can afford it, and I'm in the situation where it's been given to me, but I'm very conscious of what is wasteful.

[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.

I have memories of clouds whisking by while sitting in the pushchair on the roof of my parents' flat. I loved it! I just loved staring at the clouds and dreaming away.

I'm not one for doing the children's party version: "Hi, I'm a character in a movie and now I'm in reality!" I was doing the last shot of the film before reshoots outside their shop. I was starting my run into the frame and I thought, "You are literally ending where this began. The loop of serendipity's too much to not go in and acknowledge it." I just wanted to see the look on their faces.

When you freefall for 7,000 feet it doesn't feel like you're falling: it feels like you're floating, a bit like scuba diving.

There's no shame in stealing - any actor who says he doesn't is lying. You steal from everything.
