I love being in London, where I live, for the shops, the bars and the clubs - but I equally enjoy going to my mum's house in Ayrshire and being able to sit on a cliff by the sea.
I can't wait to work with Peter Capaldi as the next 'Doctor.' I know him from old; he's such a lovely man and will be brilliant in the role. As long as he tones down the Malcolm Tucker swearing.
I love playing 'Madame Vastra.' Although I do suffer, spending three-and-a-half hours in make-up every morning to have her lizard skin put on. I was so excited the first day when we did the make-up test, but after six hours, I was like, 'Can we finish now?'
