“It was clear from the first read-through that Peter and Jenna spark off each other’s energy. They get on incredibly well, which always helps.
They’re both incredibly conscientious and professional in their approach, and take their responsibility towards the characters very seriously. I think with the Doctor, more than most parts, the actor shapes the character and both Peter and Jenna bring so much additional depth to two already complex and beguiling roles.
I think one of the reasons the twelfth Doctor and Clara work so well is because it’s a fiery, fun but unpredictable relationship, which is what makes it compulsive viewing.”
– Nikki Wilson, Doctor Who producer
