As an actor, you are aware of how a role can seep into your real life.

I've done a bit of live action before but the fight sequences, the wire work and the physical regime were taken to another level [ in Doctor Strange].

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

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.

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 think I'm a very good driver. Apparently, the cause of road rage - as with most anger - is some kind of superiority complex, which, god knows, cars foster.

There's no shame in stealing - any actor who says he doesn't is lying. You steal from everything.
