Doctors and nurses do crazy hours and keep an ideal afloat through the love and care that they have for their craft and their patients and the institution of the NHS. We should be very proud of it.

I'm quite surprised by how many people grew up with this character [Doctor Strange ].

I've been quite a late developer on the clothes front, but I've suddenly realised it is one of life's joys.

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.

I don't live beyond my means. I enjoy luxury and I enjoy the privilege of it, when I can afford it, and I'm in the situation where it's been given to me, but I'm very conscious of what is wasteful.

I've been very lucky at what's happened in my career to date, but playing something as far from me as possible is an ambition of mine - anything from a mutated baddy in a comic book action thriller, to a detective. If anything, I'd like Gary Oldman's career: he's the perfect example of it. I've love to have a really broad sweep of characters - to be able to do something edgy, surprising and unfashionable.

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.
