The Sherlock special is set back in Victorian England, an interesting turn for the modern-period show. Steven Moffat, the series writer and creator alongside Mark Gatiss, was very excited to be able to go back to the roots of the stories of Sherlock Holmes. He really wanted the viewers to see Sherlock (Benedict Cumberbatch) and Watson (Martin Freeman) solve crimes without the use of technology. Moffat even said that they are trying to have the special premiere in select theaters.
