If I was a supervillain, I think I'd probably ban all smoking and drinking. That's exactly what I'd do: I'd remove all the cigarettes and alcohol from the world. That would piss so many people off. That's worse than, like, murdering puppies. For some people.

Suddenly, the world I had scrutinised for so long was all around me, as if I had leaned forward and climbed into the television like Alice through the looking-glass. I had no idea just how deep the rabbit hole would go.

Doctor Who was a big part of my childhood so it was a great honour to be in it.

I think we all mistake certain things for happiness. I think we mistake comfort for happiness and we mistake pleasure for happiness, and entertainment for happiness, when really these are just things we use as proxies for our happiness. We use them to cheer us up or try and achieve brief happiness, when really happiness is something much more profound and long lasting and exists within us.

A movie is a creative process from its conception, through its writing, to its execution, to the editing. I think with the best films there is some kind of contribution from one person all the way through that. The best films are made by people who write, direct, and edit, so there's continuity.

Films used to be about challenging, emotional journeys or moral questions that might make you walk away and re-evaluate how you felt about... whatever. Now we're walking out of the cinema really not thinking about anything, other than the fact that the Hulk had a fight with a robot.

Plainly it isn't an exact science, despite it being a complex interaction of micro-decisions and corresponding thought; perhaps it doesn't always work and we pass by some potential soulmates like the proverbial ships in the night, never quite connecting. Then again, perhaps the system is tenacious and continues to run like a computer program on infinite loop, so that if at first you don't meet, you are drawn back together for another try.
