I think I've had very knee-jerk emotional reactions to things, and sometimes I've said things without thinking. Being overly emotional clouded my judgment.

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.

Metaphorically speaking, it's easy to bump into one another on the journey from A to B and not even notice. People should take time to notice, enjoy and help each other.

I feel that TV and film feed off each other well. It's more in the perception of the viewer than it is of the actor.

I've never been front and centre as an iconic American character [like in Doctor Strange]. Day to day, you know you're painting on a very big canvas.

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.

I wanted to take the audience on a journey where that transition was funny and awkward. It's the same cynicism that [Strange] has.
