'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 really enjoy singing, it's entirely different to acting because I'm just being myself.

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.

Othello' was my first Shakespearean discovery. I was obsessed with drama at school, and I studied the play for my English GCSE. Desdemona is the part that everyone wants, but Iago's wife Emilia is the one I've always been drawn to.

For years, I was often afraid to speak up when I didn't fully understand a script. I'd tie myself in knots.

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've had moments of thinking maybe I should go on Twitter. It's something that I've been shy about, and I've thought that maybe I should do it.
