Some words from Russell T Davies, executive producer of Doctor Who (spoiler alert) 

About family drama on television: I have sat with a group of 15 people watching Finding Nemo on a Sunday morning – one member of the group was five and another 55, and when you see things like that happening you know that the myth that family drama doesn't exist anymore is simply not true. We were told, Julie (Gardner) and I, to be careful aiming for a family audience because it doesn't exist anymore. I absolutely didn't believe it, that's why we built Doctor Who to be an event every single week. There's something big and different so everyone can come together to watch it, not just kids, and not just adults – genuine family viewing really.
 
About the Christmas episode: Well it's an hour-long episode which is something we've never done before. It will be a great, Christmas adventure that's really big in scale. It will be Christmassy, there's nothing I like more than a Christmas Special set at Christmas! There's a big story in it for Rose as well as a massive threat to the Earth going on beneath the surface so Christmas as usual!
 
About the new doctor: David (Tennant) is like a whole new lease of life. I think one of dangers of success sometimes is that one can get too complacent. Putting David at the helm means we're all reinvigorated because we have got to be just as good, if not better just for him. So it's actually very exciting, but at the same time scary. It's back to square one for us so that's always a good place to be I think. You have to put pressure on yourself really, because you have over seven million viewers who love this show, so you mustn't let them down now. We have got to deliver even more surprises for them, and I'm absolutely confident we can do it!
 
About the second season: We have the Cybermen! We're also going to alien planets which we didn't do in the first series because I wanted to be confident of the design and now I feel sure. We also have the best design and SFX team in the world. The series will remain connected to the Earth because I think that's important. There will be a couple of old faces, and lots of new faces. Trips into history with us going back to the 1700s at one point... that's all I can say at this stage I am afraid.
