Though showrunners Steven Moffat and Mark Gatiss have indicated they have planned out the series through a fifth season, actor Benedict Cumberbatch has suggested the upcoming fourth season of “Sherlock,” which wrapped in August, could well be it for the show.
In a recent interview with GQ UK, Cumberbatch suggested the series has run its course with next year’s three new fourth season episodes serving as a capper:
“It might be the end of an era. It feels like the end of an era, to be honest. It goes to a place where it will be pretty hard to follow on immediately. We never say never on the show. I’d love to revisit it, I’d love to keep revisiting it, I stand by that, but in the immediate future we all have things that we want to crack on with and we’ve made something very complete as it is, so I think we’ll just wait and see.”
Cumberbatch adds though that he finds the idea of never playing the character again “galling” which would suggest even if he does come back, it’ll be considerably longer than the already two year or so gaps between seasons already.
