The highly-anticipated season 4 of the BBC’s modern take on Britain’s most famous detective, Sherlock Holmes, is finally seeing the light on January 1st, 2017.
Gatiss then takes us to a read-through, where we can briefly see Sherlock Holmes himself, Benedict Cumberbatch, as well as John Watson (Martin Freeman) and the always merry Mrs. Hudson.
The one-minute video seen above takes us back to April, to the first week of filming Sherlock’s season 4.
Mark Gatiss serves as a sort of tour guide at Pinewood Studios in Wales, where we can see the crew hard at work building the sets.
