Steven Moffat has said that it was “time to get rid of” old Doctor Who.
Speaking to Empire Magazine, Moffat said: “It was time to change. Certain things we were doing a little reflexively. Some of the humour was getting a bit glib. One of the hardest things to notice is when your new idea has become your old idea and it’s time to get rid of it.”
Jenna Coleman added: “It’s amazing how different it feels. It’s darker. The limits feel like they’re being pushed more in terms of the danger and the dread. It’s scarier, that’s for sure.”
Coleman said one of the bigger changes is the pace of the stories: “A producer once told me this is the hardest job because you’re creating characters and telling stories while always on the run. But Steven’s changed the format quite a lot. We have much longer scenes now.”
Ben Wheatley, director of the first two episodes, said: “For me, they’re back to Classic Who, or the mid-Tennant adventures, where you’d tell a story and move on to the next one, less tied up in the final machinations of long plot arcs.
“Capaldi’s his own man but there are elements of Baker and Troughton and Pertwee. He’s inherently funny but inherently brooding and complicated, as a performer and a man.”
Doctor Who Series 8 will begin on Saturday, 23rd August on BBC One.
