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

I love cycling, but if I could find a way of building something above the streets for cyclists, that would be amazing. We need even more space.

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 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.

I love discovering tiny streets.
