American publication The Hollywood Reporter interviewed Steven Moffat on the set of the 50th anniversary special, The Day of the Doctor, and the showrunner revealed a few new tidbits on the anniversary adventure.
“It’s quite a dark episode. It’s quite a serious episode. We start to move the Doctor into a place, and you’ll start to see we’ve been moving him into that direction for a while The question was: what was the most important thing that happened to the Doctor, the day the Doctor won’t forget. It will redefine him.”
“I knew what I wanted to accomplish. It is a tremendous challenge to attach 50 to anything. I wanted it to be the show that ensures the next 50 years. And it celebrates the legend.”
Moffat also stated that despite the rumours of him departing after Series 8 next year, he has no intentions of leaving just yet.
