Cumberbatch - it sounds like a fart in a bath, doesn't it? What a fluffy old name. I can never say it on a Monday morning. When I became an actor, Mum wasn't keen on me keeping it.

I thought, well, why am I giving up on my primary dream to work doubly hard, to do something as an alternative to what it really still want to?

It's one of the things that attracted me to the role [Doctor Strange] is the fact that it's a really widely origin story, I mean this is part of it, but of course there's the whole chapter before where he's the neurosurgeon who has the accident. It's fantastic.

I was never geeky about anything.

[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.

I'm not confident in social situations; just going up to someone in a bar and saying 'Hi' is going to be even more difficult because they won't know the real me. They will just know me as a fictional person I play on the screen.

I had to imagine myself into certain aspects of [Julian Assange] character for our version of events. That involved extrapolating based on clues in his biography, his public persona, photographs, and other accounts of him by people who encountered him during that extraordinary period from 2007 to 2010 that we charted in the film [The Fifth Estate]. So, it involved a lot of research but, sadly, no contact with the man himself.
