If Julian Fellowes was set to music he’d be Gustav Holst’s Jupiter, the bringer of jollity. “I like everyone to be happy,” he says. “I love happy things, I never want to be unkind.” I have never heard him say a common or mean thing about anyone. Like Denry in Arnold Bennett’s comic novel The Card, Fellowes is “the great cause of cheering us all up.”

So far Fellowes has cheered us with Gosford Park, for which he won the Oscar for best original screenplay; two novels, Snobs and Past Imperfect; films; television performances; and, of course, Downton Abbey. The series finished in 2015. Cue abandonment issues from an estimated global audience of 120 million.
