“I love doing impersonations of people.”

Laughing and crying are really similar – what happens to your body. It’s a very similar process in your diaphragm. Like a musician, you have to do your scales once in a while and warm up your voice.

I always seem to be cast as slightly wan, ethereal, troubled intellectuals or physically ambivalent bad lovers. But I’m here to tell you I’m quite the opposite in real life. In fact I’m a f**king fantastic lover.

My own grandfathers were a submarine commander and a ‘desert rats’ tank operator in the Second World War.

I suppose my bodily proportions are quite flattering. I’m ripped, doing something I wouldn’t normally do with my body, or having done to it, involving Watson.

I keep myself amused and others confused

I just increasingly enjoy the quiet moments when I can be on my own with my friends and family, or with a book, having a live experience. That’s really what I crave, and I always have done.

As an actor, to be part of that story’s [Marvel univerce ] terrific. I’ve enjoyed it so much as a fan and now I’m getting to have a go myself.

When I was young I became kind of a party animal. I had a massive crash. My health suffered. I was just overdoing it. That person could not be further from the one who emerged from that earlier experience. I regressed massively.

I’d shift disciplines, whether it was musical instruments or sports or whatever, and it’s the same with that.

There are things that are a given, that you’ve already established, and obviously, visually, certain iconic things that can’t be completely removed, like a certain hat or a certain coat in my case.

New York City is crazy and beautiful and really close to my heart, and I’ve always had dear friends here – family, actually, I would say.

[Season 4 of Sherlock Holmes will be] myopically dark. You’re talking about the end of the universe darkness. You can’t see in front of you and would walk into everything dark.

It’s the same thing, I think, whether it’s breathing or meditation or yoga. And running is a great way of doing it.

Do I like being thought of as attractive? I don’t know anyone on Earth who doesn’t, but I do find it funny. I look in a mirror and I see all the faults I’ve lived with for 35 years and yet people go kind of nuts for certain things about me. It’s not me being humble. I just think it’s weird.

Any irrational fears?no, i’m quite a rationalist. i’m not superstitious, i think life is too full of natural wonders and logical complexities to worry about illogical things.

Do awards change careers? Well, I haven’t heard of many stories where that’s the case. It’s a fun excuse to meet colleagues and celebrate people who’ve done well that year in certain people’s eyes, and it’s nothing more than that.

As soon as you make anything that people like, you get all these new artists hitting you up like ‘I want to sound just like Billie Eilish.’ And I’m always like, ‘Absolutely not.’

There is a very thin line dividing characterisation from impersonation. I’ve to make sure I don’t cross over into mimicry.
