“I’m shocked at the speed at which it’s going. I’ve done 26 episodes already, and I don’t know how that happened.Doctor Who returns to our screens with The Husbands of River Song on Christmas Day at 5.15 p.m. on BBC One.
I’m amazed that people ask me all the time, when I am going? It makes you feel very unwelcome! ‘Please, when are you leaving?’ Or…someone said this morning, ‘You’re only doing six episodes next year because you’re too tired?’ I don’t know where they’ve made this stuff up from. Six episodes?! That’s not what I’m contracted to do.
And I would do 20 episodes if they let me. I could do Doctor Who all the year round, quite happily.”
