‘No, I don’t get angry. I get quite prickly if someone insists on going there. But I’m totally aware that’s their job. And I completely understand why people are interested in that, because I am too. One has a human, slight prurient interest in who people are shagging. I don’t blame them for asking the questions, but dodging them can get a little tiresome.’

‘I get a bit nervous, well, nervous is the wrong word, but I always feel like I disappoint, because I’m a just a bloke from Paisley, do you know what I mean? Obviously, one is polite and gives autographs and is smiley and nice and you try to be as exciting as you can, but I’m never gonna be as glistening bumping into some kid on the tube as they want me to be. But I have to say, all the kids that have come up have been so lovely and excited and that’s been great. It doesn’t seem to have been a problem for them. It’s probably more of a problem for me. It’s easier on set, because then you’re in costume. You don’t want to disappoint, but at the same time you don’t want to pretend I’m really the Doctor, that would be mad as well!’

‘I’ll be very well behaved, until my second glass of wine hits – then I’ll be anyone’s!’

'I didn't expect to get Casanova at all. When I saw the list of people up for it I thought, "Oh well, it will go to the beautiful boys." [Interview asks: And that's not how you see yourself?] I don't think I am, no. What?' [Interview asks: Have you not read any of the press that's put you in that category?] I genuinely don't think I am, I've never read anything that suggests I might be ... whatever you're suggesting. 'I think that's precisely why I got Casanova, because they didn't want that, they wanted him to be a cheeky chappie - that's why his love rival is Rupert Penry Jones, who's 6ft 2in. It was all about the wit and the words.'

‘I've been watching Doctor Who since I was 3 years old (along with just about everyone else of my generation who grew up in Britain), so I had probably made a whole host of unconscious decisions about how I was going to do it years before it was an actual possibility. But to be honest, when it actually happened, I didn't sit down and draw up a list of quirks that I wanted to fit in to my performance. As with any other part, you take your lead from the script and what that character says and does. Once that is filtered through your own perspective and experiences, then hopefully it will be particular and unique. I was always aware of avoiding any kind of self-conscious eccentricity. The Doctor may be a 900-odd year old Time Lord from the other side of the galaxy, but he still has to be a believable character, or the whole thing collapses.’

‘ To be honest, I'm so caught up in making the show down here in Wales that I'm not always aware of what it's doing around the world. I've heard that Canada have taken to us in quite a big way, which is great, a s I've got family there. I believe we've also sold to South Korea, which isn't the first place you'd expect to find Doctor Who, but I'm delighted that it's there. I'm not sure of all the other countries that have taken the show, but it would seem to be just about everywhere. And, of course, I'm really chuffed that we're showing in the States now, too.’

"I've always been preposterously single-minded about my career. I was three years old when I decided I wanted to be an actor. I just loved watching people on the telly. I was watching stories being told and thinking 'this is just great'. I think I had a conversation with my parents about who these people were in the TV and as soon as I had an understanding that this was a job, that people got paid for telling stories, that was what I wanted to do."

‘I know I shouldn't say this, but I still find it impossible to believe that anyone in the arts votes Conservative. I want to say: 'But you spend your life doing stuff about the human condition. How can you be in a production of, say, King Lear, and vote Tory. Did you not understand it? Or did you just not like it? And if you think Shakespeare got the whole thing wrong, how can you square what you're doing with yourself ?'”

‘When I started working in theatre in England, I would meet people, and they would say 'Oh, I voted for Margaret Thatcher.' he first time I heard someone saying that, I honestly thought they were joking. I'd be thinking, 'I have never met anyone from your world. What's it like? Do you roast children over open fires?'"
