Doctor Who’s days with Steven Moffat at the helm are coming to an end.

In an interview with Radio Times, Moffat confirmed that he’s “actively” assisting in finding someone to take over the reigns of Doctor Who.

Moffat said he’s “actively engaged in a search for a new showrunner” but “can’t say much about that.”

One of the issues appears to be the emotional struggle of leaving a project he took over from Russell T. Davies, and helmed through the fiftieth anniversary celebrations.

“Everything is difficult in Doctor Who, including leaving, and I would never do anything to harm it. I would never leave it in the lurch because it means too much to me. Yes, it’s a problem. Let’s not pretend it’s not a big problem. But there will be a solution. In terms of the emotional difficulty of leaving, it’s hard,” he said.

Moffat’s departure may not be coming in the very near future, but it does appear to be inevitable. “I won’t be leaving because I’m suddenly miserable,” he added. “It’ll be because I want to do something else.”

He noted that he’s taking the show one year at a time.

Elsewhere in his interview, the showrunner offered an update on the Doctor’s new companion following the departure of Clara in series 9.

“I’m beginning to have an idea of the kind of person, specific ideas but not a specific actress,” he said, hinting that it would be a new person. “A new companion gives us the chance to launch the show again. It began in 1963 with the story of Ian and Barbara and then in 2005 with Rose Tyler. Arguably it begins again with the story of Amy Pond. You can recruit new viewers when somebody else meets the Doctor. And I think we’ve got a really cool new idea about how to do that.”

Steven Moffat’s departure from Doctor Who is one of the headlines we said we want to see in 2016.
