I think expectations of 'Doctor Who' should always be high, because it's a show that must always progress and get better and better.

I think that, if the world was a bit more like Comic-Con, we'd all be a little happier.

We didn't start Theocracy because we wanted to be cool like so-and-so and make money. Our songs aren't trendy, and our lyrics hopefully make people think about certain concepts in a new way.

I think that every artistic venture is a risk, and it has to be that way, so you do as much preparation as you can and make that as thorough as you can possibly make it, until you turn up on set. It's about taking risks, and some might work and some might not, but that's what makes it interesting.

I can’t think of anyone else I’d travel around the universe with than Amy Pond.

I think Jennifer Saunders would be great in 'Doctor Who.'

There’s rivalry between the Harry Potter fans and the Twilight fans. And Twilight fans think they’re much cooler than the Harry Potter fans. And I’m like, I dunno why, they’d all get their butts kicked by the Doctor Who fans.

When you think about it, we’re all different people all through our lives, and that’s okay, that’s good, you’ve got to keep moving so long as you remember all the people that you used to be.

It's been four years. It's been the best four years. It's been wonderful, it's been a privilege to work under Steven Moffat. But I think when you gotta go, you gotta go It's sad, I'm going to miss it. I'm going to miss Comic-Con as well. It wasn't an easy decision, but I dunno, you can't play it forever. And, look, they'll get someone amazing and brilliant, and that's the great thing about the show. It continues, and it will get bigger and better. And you'll forget about me.
