Filming for series four of Sherlock is underway in the UK.
Confirmation of production only emerged recently after co-creator Mark Gatiss (pictured) hinted about it on social media.
The new series promises three feature-length episodes with Sherlock Holmes, back in the present while Doctor Watson and his wife, Mary, will become parents for the first time.
Star Benedict Cumberbatch said he was “genuinely thrilled to be back filming Sherlock with all the cast and crew. I can’t wait for everyone to see season four. But you will have to wait… though not for long… And it will be worth it.”
Co-creators, writers and executive producers Steven Moffat and Mark Gatiss said: “Sherlock series four – here we go again! Whatever else we do, wherever we all go, all roads lead back to Baker Street – and it always feels like coming home. Ghosts of the past are rising in the lives of Sherlock Holmes and John Watson bringing adventure, romance and terror in their wake. This is the story we’ve been telling from the beginning. A story about to reach its climax…”
Sue Vertue, Executive Producer for Hartswood Films, says: “It’s taken a while to gather everyone together for series four, but I can confidently say I think it will be well worth the wait!”
It isn’t clear if “climax” also means an end for the series, due in 2017.
The first episode will be directed by Rachel Talalay, who has previously directed Doctor Who, The Flash and The Wind In The Willows.
