As you might expect, Benedict Cumberbatch is currently actively engaged in promoting "Doctor Strange," the film in which he stars as the titular Marvel Comics hero. But in an interview for the British edition of the monthly men's magazine GQ, the actor let slip his thoughts on his other fan-favorite role as the star of the BBC TV series "Sherlock," which recently concluded filming its fourth season.

“It might be the end of an era. It feels like the end of an era, to be honest," the actor stated. "[Season 4] 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. The idea of never playing him again is really galling.”

All of which seems suitably ambiguous, although it has also been reported that "Sherlock" showrunners Steven Moffat and Mark Gatiss have already plotted out the show through to season 5.

Exactly when that might be filmed and released currently remains a matter for speculation.

“Doctor Strange” arrives in theaters on November 4, and Season 4 of "Sherlock" is expected to be released in 2017.
