I've never been front and centre as an iconic American character [like in Doctor Strange]. Day to day, you know you're painting on a very big canvas.

Those are more universal things than some of the characters I play, who are slightly sociopathic. I keep reminding people I can do ordinary.

For brain surgeons it's particularly difficult to deal with failure. It was fascinating to learn about that whole world.

I struggle to learn by rote. I've had meltdowns on set. Which is embarrassing and shameful.

I just want to bring people in a little bit to the idea of sitting down on a Sunday three consecutive weeks and having that water cooler moment that really was a sort of a national sensation in the U.K., 'cause it's kind of fun.

I drag a lot of stuff round with me that I don't need.

Any privacy in public is a hard thing to negotiate.
