What have we got to look forward to in series 10?
The show is down to the basic elements which are these fairly innocent but independent companions travelling with this mysterious creature from outer space who can travel in space and time and take them to the most amazing corners of the universe where they meet terrible monsters who try to kill them. That’s at its very simplest level but obviously it’s more complex and there’s more to it than that but that’s pretty much what we do every week. Some seasons have been less like that but this season very much follows that model of delivering every week – the mysterious creature takes the companions to an exotic and dangerous place.Pearl Mackie
Who is Bill Potts?
Bill is cool - she’s quite young, doesn’t really know much about the world. She’s very real - she’s not had a very easy upbringing and whilst she doesn’t really let that affect her day-to-day life, it’s there under the surface - she can be quite defensive. She’s fun, she’s excited, she’s a bit geeky - she quite likes sci-fi stuff, she’s into space and that type of thing so when she does go on adventures with The Doctor and discovers aliens are real and that kind of stuff it blows her mind which is really cool.
Has Nardole changed now he's a regular traveller in this series with The Doctor? If so how?
I feel he has. He’s more textured, more three-dimensional. You couldn’t go through a whole series with him being as cartoonish as he was in The Husbands Of River Song. That episode was played for laughs because it was a Christmas Special. We get to learn more about him and why he’s there. He has a purpose.What's his relationship like with The Doctor now?
They bicker. He works for The Doctor, but he’s never afraid to take him on either. He’s not shy in saying when he disagrees with something, and sometimes he’s just grumpy because he hasn’t had enough sleep. He definitely prefers the quieter life.Steven Moffat
What new and returning monsters do we have to look forward to?
By nature I’m just excited about all new monsters but we’ve got some wonderful stuff! We’ve got a serpent that lives under the Thames in the shape of the Thames which, now that you realise it, the EastEnders title sequence has always clearly been about a giant snake.
We’ve got the emojibots which are small, cute and communicate by emojis and turn you into skeletons so that’s brilliant. We’ve got the most shiver-making creatures in Mike Bartlett’s episode - not going to tell you what they are because the show teases you a bit about what’s going on but I guarantee there are moments that will make you go “URGH!” as I’ve been looking at some of the effects for episode four and you think “Oh my god are we putting that on television?!” It’s really properly gross and magnificent. We’ve got a new enemy, which I won’t talk too much about but we call them The Monks though that’s not really their name. We’ve got a fabulous Scottish creature care of Rona Munro - The Eater of Light. The Ice Warriors are back with a new wrinkle and of course Missy is there - always with Peter Capaldi’s Doctor - he’s up against Missy, tested and teased and entranced by his oldest friend and wickedest enemy.Series 10 begins next Saturday with The Pilot.
