“It was a confused launch,” Davies wrote. "We knew it would be, but there was no way around it. It was the sixtieth anniversary, which meant going to a streamer to say this is a brand-new show that’s celebrating sixty years. It’s launching and regenerating at the same time. Quite a difficult concept. I think that f****d it from the start.

“Disney’s solution was to throw away the three anniversary specials, more or less. They dropped them on to the platform, but they didn’t really advertise them. I don’t think David Tennant did a single interview with the American press. And I accept that, because we’d created that oddness. But it was a stumbling start in America, from which I think we never quite recovered.”
