I'll always do 'Sherlock' - it's something I'm not going to give up on.

Fame is a weird one. You need to distance yourself from it. People see a value in you that you don't see yourself.

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.

When you freefall for 7,000 feet it doesn't feel like you're falling: it feels like you're floating, a bit like scuba diving.

Lines are very difficult to learn.

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.

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.
