Behind the scenes
Sherlock was co-created by Steven Moffat and Mark Gatiss, and written entirely by them and Stephen Thompson. Sherlock and Doctor Who share many other crew members, as well.

Starring Benedict Cumberbatch as Sherlock Holmes and Martin Freeman as John Watson, Sherlock retells Arthur Conan Doyle's classic stories, in a modern setting and original storyline. The series also stars Gatiss himself as Mycroft Holmes, Rupert Graves as Inspector Lestrade, Louise Brealey as pathologist Molly Hooper, and Una Stubbs as landlady Mrs Hudson.

Some other notable common actors with DWU productions are Vinette Robinson, Lindsay Duncan, Russell Tovey, Phil Davis, Tim McInnerny, Eleanor Matsuura and Gemma Chan.

Rachel Talalay, Euros Lyn, Toby Haynes, Douglas Mackinnon and Colm McCarthy have each directed Sherlock episodes. Nick Hurran has directed two.

Fandom for Sherlock and Doctor Who was often interconnected with each other, frequently leading to fan content celebrating the shows together, often by crossing them over with each other (the term "SuperWhoLock" tended to be used with this mixed fandom activity, which included fans of the American dark fantasy drama Supernatural). A prominent example of this was the short film Wholock, depicting Sherlock meeting the Eleventh Doctor, made by Ben Pickles under his John Smith VFX YouTube channel, prior to him working on Doctor Who officially.

The Sherlock versions of Holmes and Watson appear in Sprout Boy meets a Galaxy of Stars alongside the Twelfth Doctor.
