'Downton Abbey' has become this huge thing, and I really enjoy the success of it, but I sometimes find myself on the outside looking in, which is sort of a healthy way to look at it so you don't get too caught up in it.

I think some period drama can be quite alienating, but 'Downton' isn't. This is going to sound quite, um, pretentious, but someone said that it's like a soap written by a poet.

I can be so blown away by story lines.

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.

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 come from a very working-class background, so my family would have been downstairs in the past, as opposed to upstairs. People are often quite surprised to hear that, that I'm not actually posh.

I get so excited about reading a new script.
