Am I athletic? In my dreams.

The press mainly want to destroy a program by revealing what's coming up. For some reason, soaps like doing that.

Julian Fellowes doesn't come to the set, except maybe once every six weeks, for whatever reason. He's not a producer, in that sense. But if you write him a one-line question, he'll write you a three-page answer.

We were all expecting to finish [Downton Abbey] after Series 1, actually. And then, it got extended to Series 3, and that's when two of our much loved and much missed friends left. And then, it was going to be done with Series 5, but Julian Fellowes said, "I'd like to do one more." So it's been a series of extensions, rather than wondering how much longer we can go on for.

For the last episode [of Downton Abbey], you'll need some handkerchiefs. I needed handkerchiefs reading it. It wasn't because it necessarily moved me while reading it, but it was the experience of reading it when I realized it was the last time I was ever going to be reading one of those scripts. That was quite terminal.
