I'm a Prince of Wales Trust ambassador, so I'm all about giving youth an education, a voice and a chance to not take the wrong road.

My mum and dad had worked incredibly hard to afford me an education.

Kevin Feige said to me: "I don't think we've ever put an actor through quite as much as this, physically and mentally." I'll wear that as a badge of honour. It was endless.

I think the characters are supposed to be an open book, blank canvas.

I was the boy that turned a girlfriend into the most celebrated lesbian on television. I got so much stick for that.

The world of 'Sherlock Holmes' and the world that we live in now is big enough to take more than one interpretation.

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.
