It really depends on the director. I think quite often, it's not what you expect. The most serious film can be the most fun. The one that's supposed to be fun can be the most serious. I don't think there are any hard-and-fast rules. I just think it really depends on your director and what the general vibe is.

I've always been attracted to cars, and driving is a completely measurable experience: if you qualify last on the grid, you're the slowest, and if you qualify first on the grid, you're the fastest. So no one can say you're slow if you're fast and no one can say you're fast if you're slow.

I guess I'm a very keen observer, and I'd like to think I have a good imagination.

The notion of people commenting on you, the notion of people saying things about you, people liking or disliking you and getting into your business, has become more of a reality for the general public over the last years, as people have dipped further into Facebook, Twitter, Instagram and social media.

When I was a kid, I would do stupid things on my bike. I'd jump any ramp, I'd jump over people, I'd jump over things - always crashing, never hurting myself badly but always wanting to take physical risks.

My background was producing and writing and performing in television when I started out, and I really missed that, that whole creative process that comes from sort of 'me' storytelling.

The movies people don't talk about or remember after six months' time don't really matter.
