For me writing and filmmaking is a therapeutic process. It reflects themes that I'm going through at a time in my life.

Red Bull are backing a spinal-injury research charity called Wings For Life, which I am an ambassador for, with a programme called Faces for Charity that will run at this year's British Grand Prix.

I don't really know what I'm ever looking for, it's kind of like whatever happens to resonate at the time with me.

Sitting beside the pool is fine for two weeks, but after that I think it'd be quite hard to live with - so I need to keep racing.

Formula one is very one-dimensional in terms of what we do in the cockpit.

For me to train and get ready for racing, I can't just sit in the gym all the time and that's the way it is. Responsibility starts and stops with me. My main gig is grand prix driving, that's what I do and I need to keep that in the forefront of my mind.

The first film I directed (Explicit Ills), I did when I was like 27 years old. I had been an actor for a certain amount of time, and then I was like, "I want to start directing."
