I thought, well, why am I giving up on my primary dream to work doubly hard, to do something as an alternative to what it really still want to?

This is an odd profession, and sometimes people get jealous, but I haven't really experienced any of that. Everyone's been really happy for me, which is really, really great.

'Sherlock' fans are, by and large, an intelligent breed, so they've gone through my back catalogue and got what I've done, why and how I've done it. There is some obsessive behaviour, but I worry for them rather than me.

[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.

It was great. I got to hang out with him [Martin Freeman as Bilbo Baggins], and I kept a straight face for a bit and then I started giggling because I know Martin, I don't know Bilbo. For Martin to be sitting there playing Bilbo is amazing. He's going to be amazing, he's going to be fantastic in this film.

Sometimes being away, on location, I feel like I'm away for much of my own life. I want to be better at staying connected.

I think playing any iconic role when you're stepping into big shoes, into the shadow of people who have come before you and you can't process that.
