I love doing impersonations of people.

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.

[Sherlock Holmes] has to understand the world. That's very much John's [Watson] influence on him. But like a lot of the friendships and relationships in that world, it's born out of necessity. It makes him better. There's a pragmatism to it. It's not whimsical or sentimental. It's born out of necessity.

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.

Look at you lot, you're all so vacant, is it nice not being me it must be so relaxing.

As an actor, you are aware of how a role can seep into your real life.

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.
