Space excites me. My dream is to go to space.

I want to be like Robin Williams, really. It's all the different characters he does, all the different voices.

How do you create chemistry? If only I knew that! Some people say it's a natural thing that you have with someone, and maybe it is to do with that, but I think you can work on it.

I wanted to be as authentic as possible because, first of all, Jean Shrimpton is still alive. And, she's interesting enough to be played accurately. I didn't need to add things.

Being in 'Doctor Who' has been so amazing. I don't think I will ever have a job quite so fun ever again. I feel sad because I am going to leave, but with any story, it has to come to an end.

I have no sense of being famous - you're just working. And then you'll have a random day in London when you'll do some press and it creeps into your awareness that this goes out - that what you do every day goes out to televisions right across the country.
