Sherlock Season 4 begins filming with Benedict Cumberbatch

“We all have a past. Ghosts. They are the shadows that define our every sunny day…”

The BBC is reporting that filming for series four of Sherlock, the multi-award-winning hit BBC One drama produced by Hartswood Films, has started. Sherlock will return to screens with three brand-new episodes promising laughter, tears, shocks, surprises and extraordinary cases…

Series four begins with the nation’s favourite detective, the mercurial Sherlock Holmes, back once more on British soil, as Doctor Watson and his wife, Mary, prepare for their biggest ever challenge – becoming parents for the first time.

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.”

The first of the three feature-length episodes will be directed by Rachel Talalay, who has worked as a director, producer, and professor in film and television for more than 25 years, having previously directed “Doctor Who,” “The Flash” and “The Wind In The Willows.”

Co-creators, writers and executive producers Steven Moffat and Mark Gatiss say: “’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!”

“Sherlock: The Abominable Bride,” which aired on New Year’s Day this year, was the most watched programme over the festive season with 11.6 million viewers and the highest-ever audience share for a Sherlock episode. The Victorian special was also released in thousands of cinemas around the world to complement the TV broadcast.

Sherlock is written and created by Steven Moffat and Mark Gatiss, and inspired by the works of Sir Arthur Conan Doyle. Sherlock is produced by Sue Vertue and the executive producers are Beryl Vertue, Mark Gatiss and Steven Moffat for Hartswood Films, Bethan Jones for BBC Cymru Wales and Rebecca Eaton for Masterpiece. It is distributed internationally by BBC Worldwide.
