At the Sherlock panel at San Diego Comic Con, the BBC and co-producer PBS released a new image and the first trailer for the upcoming Victorian era special.
The new special is not part of the greater continuity of the series and is instead set in the Victorian era, as are the original stories by Sir Arthur Conan Doyle. All four primary cast members (Benedict Cumberbatch, Martin Freeman, Una Stubbs and Rupert Graves) will appear. While few plot details have been revealed, it was announced at the panel that, in addition to airing on BBC One and PBS, the special would also get a limited release in select theaters around the globe.
The 90 minute special was commissioned by BBC One Controller Charlotte Moore and the then Controller of Drama Commissioning Ben Stephenson last year and is expected to premiere towards the end of the year, most likely at Christmas (though it’s worth noting that showrunner Steven Moffatt was far less specific, saying only that it would air some time “in the next year”). A three episode fourth season is then expected to follow in 2016, with pre-production at a very early stage at present.
