Official confirmation has arrived that Series 4 of Sherlock will shoot in the spring of 2016 – the sort of new news we kind of already knew.

As Knowledge readers will know, we have been following the activities of a certain Mr B Cumberbatch with interest of late, and with the recent confirmed start date on Marvel’s Doctor Strange, it seemed likely that he would not be freed up from playing the Sorcerer Supreme for some time.

There is a confirmed line producer on board the fourth series of Sherlock, who will be listed on Production Intelligence once they have finished their current project. Sue Vertue produces the three-part run, with scripts once again by Mark Gatiss and Steven Moffat.

The fourth series has been detailed on PI since January; non-subscribers can click here for a demo.
