I had dance training from a very young age, 3 or 4... It taught me how to present myself, about preparation and working in an ensemble, and its something that carries with me to this day.

I don't mind wearing a corset; it informs your posture, changes the way you move, you can't slouch.

I think the first time I realised Downton Abbey was a hit was when I was sitting in a tea shop in New York and the couple next to me were talking about Downton Abbey, and then they recognised me.

The last time I cried? My godchildren went to see Taylor Swift in concert and got to meet her. They literally ran toward her and hugged her, and it was amazing. I got big bonus points for it. I'll remind them when they're teenagers.

I think the success of 'Downton' is partly because there are effectively 18 leading characters, all given equal importance, so it's enormously involving on many levels. But also, it's a new story. It's not like Dickens or Austen, where everyone knows the denouement.

I get so excited about reading a new script.

Shakespeare and his work will always be relevant. He wrote those pieces hundreds of years ago and we haven't really changed as humans, have we? We have to deal with love, honour and adultery now - people were the same then, too - that's what's so wonderful and powerful.
