Filming begins on Sherlock S3E2: The Sign of Three

Principal photography has begun today on the second episode of Sherlock Series Three.

Sherlock S3E2: The Sign of Three

Written by Stephen Thompson, Directed by Colm McCarthy

The episode will film over the next few weeks and will complete shooting next month. Following the wrap on The Sign of Three, a long scheduled break in production will occur to allow cast and crew to fulfil other commitments. Production will then resume later in the summer with the filming of Sherlock S3E3. The final episode in Series Three will be written by Steven Moffat, but the director is currently unannounced.

As previously noted, this is the first time the episodes in a series of Sherlock are being produced in episode order. Series One saw production begin with S1E3: The Great Game, followed by S1E2: The Blind Banker and S1E1: A Study in Pink, while Series Two commenced with S2E2: The Hounds of Baskerville, then S2E3: The Reichenbach Fall and S2E1: A Scandal in Belgravia.

And finally, as we said when S3E1: The Empty Hearse started production, these are our promises to our readers:

- We will never reveal ANY plot spoilers for the new series ahead of the broadcast of the new episodes unless they are officially sanctioned for release by the production team.

- We are not able to publicise any location filming that we may become aware of ahead of time due to issues of confidentiality, and the possibility of impacting the work of the cast and crew. Large numbers of people standing in a crowd have the potential to affect the filming, and we will be trying our best to ensure the crew has a minimum of disruption.
