I was in the National Youth Theatre, too, but there was no dancing there. I was doing plays like 'Julius Caesar' and playing the lute very badly.

I really want to emphasise this - 'Strictly' is a positive show. It's interesting that it gets cast into this, understandably, the ordinary net of reality shows, but there's no part of it which feels nihilistic or unpleasant. It's all about learning something and doing well, and you feel this overwhelming sense of people wanting you to do well.

Learning about crime in great detail forces us to ask ourselves how it happened, how the victims and perpetrators got to that point, how the law works, how the police force functions.

I used to deal with high-profile criminal cases that were covered extensively in the media, and one of the things I quickly appreciated was there was a gulf between what really took place in the middle of a case, the impact on victims, the effect on the police and how they solved crimes, and the way it was reported.

I've worked with David Lynch since I was 17, and working with him is home and family; being around Alexander Payne is home and family, Jonathan Demme. There are directors... Robert Altman, Paul Thomas Anderson... They are directors where I create homes.

I haven't strength of mind not to need a career.

Sadly, it runs in my damn family, and that disease is a mystery to just about every scientist! We are definitely interested in finding a cure for ALS! Cure it already!

Even if I don't have a job, I work on plays and scenes.
