I am shortsighted. I need glasses for watching movies or concerts. It's not a hipster affectation; I do have poor eyesight. This is how ridiculous my life is: I've had the test for contact lenses, but I haven't found a half-day where I can go to the optician.

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

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.

I really cannot get over the generosity of our Tibetian teacher. He said, "Don't punish yourself. You're going to be a student at a university in the north of England. You need to have your experiences and have your fun, and not judge yourself. Don't live in guilt and regret."

Even the cerebral characters I play seem to have physical quirks. They're all "physically inhabited," for lack off a better expression. For instance, Sherlock Holmes has very particular physical gestures which are drawn out in such detail.

The armoury of having any academic education does not necessarily set you up for being a good or better actor.

Maybe it's just getting older, but I don't want to miss things.
