I wanted to take the audience on a journey where that transition was funny and awkward. It's the same cynicism that [Strange] has.

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.

Maybe it's because I was an only child, but I've always wanted kids.

To get a horse to hit a mark without a rider, to get it to stand up, to get it to rear, to get it to pick up a bucket and bring it over is amazing. It's hard work and very rewarding but can be dangerous.

I'm not one for doing the children's party version: "Hi, I'm a character in a movie and now I'm in reality!" I was doing the last shot of the film before reshoots outside their shop. I was starting my run into the frame and I thought, "You are literally ending where this began. The loop of serendipity's too much to not go in and acknowledge it." I just wanted to see the look on their faces.

I am very flattered. I have also become a verb as in "I have cumberbatched the UK audience" apparently. Who knows, by the end of the year I might become a swear word too! It's crazy and fun and very flattering.

My first agent dissuaded me from calling myself 'Cumberbatch.' I had six months of not very productive time with her, so I changed agents. The new one said, 'Why aren't you using your family name? It's a real attention-grabber.' I worried, 'How much is it going to cost to put my name in lights?' But then I decided that's not my problem.
