“[Doctor Strange ] is slightly more specialised than Spider-Man or Superman or Batman, but he’s very loved by people who know him.”

I understand from those who adore him, he [Julian Assange] has a great sense of humor which rarely gets an airing because he’s dealing with such serious issues.

My mum and dad had worked incredibly hard to afford me an education.

[on BBC’s Sherlock] It’s a rare challenge, both for the audience and an actor, to take part in something with this level of intelligence and wit. You have to really enjoy it. It’s a form of mental and physical gymnastics.

[ Stephen Strange] is less strange than other characters I’ve played. He’s lost the power to love, which doesn’t make him a nasty person. I just think he’s closed-off.

Because reading is one of the joys of life, and once you begin, you can’t stop, and you’ve got so many stories to look forward to.

It’s always important to have the blessing.

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.

I really cannot get over the generosity of our Tibetian teacher. He said, “Don’t punish yourself. You’re going to be a student at a university in the north of England. You need to have your experiences and have your fun, and not judge yourself. Don’t live in guilt and regret.”

Enjoy the journey of life and not just the endgame.

Even though Doctor Strange is an established character, when you’re doing an origin story there’s a lot of room for manoeuvre.

It is a wonderful thing to get married young and become a father.

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

It’s an interesting arc. You start with a character [Doctor Strange] who’s likeable and charming but very arrogant and distant. He’s funny but you can see there are massive holes in his life. It’s a very painful transition and all that he becomes is tested so quickly and violently.

I did a lot of acting at school and university, then I went to drama school. It was quite a normal route.

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.

Landing the role of Stephen Hawking was the most positively surprising thing that has happened to me.
