I was very nervous about doing the Entertainment Weekly cover, because I thought, "Okay, this is the first taste, this is the first visual moment." By then I obviously knew a lot of the more iconic moments in his comic history, but still it's me. It's not a drawing, it's not an artist; it's me and I'm kinda frightened, but it seemed to go down.

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 had parents who were working actors, who did really well in their careers, but it was a living. So it was a reality for me growing up; it wasn't a fantasy. It wasn't sitting there going, "I want to be adored." It wasn't that at all. Not to say that the screams of fans aren't a smile-raiser, but that was never the pull for me.

I've said for quite a long time I'd like him to have a different haircut. I quite like my hair being short. You know, we've been away two years, let's f*** around with his outfit, let's f*** around with his haircut, let's do something different.

I think the characters are supposed to be an open book, blank canvas.

Sherlock [Holmes] is on the side of the angels, but don't think he's one of them. He uses similar means, but it seems to be for a better purpose, one would hope.

I've never done a lead role in a film this big [like Doctor Strange], in a franchise this big. One of the reasons was, I wanted to know what the toy box was like. And it's just insane, the amount of facility that everyone gets, but the amount of artistry and craft that's brought to every aspect of filmmaking. I mean, you go to your first costume fitting and it's one of thirty. It's a myriad, but it's for a reason. There are so many incredible costumes in this.
