‘The Sherlock Special’ Trailer with Benedict Cumberbatch and Martin Freeman

“Sherlock” is a contemporary adaptation of the Sherlock Holmes detective stories by Sir Arthur Conan Doyle. Really they should have just made the full thing a bigger budget theatrical movie, although the production design and period detail looks impressive enough as it is.

The BBC is billing this as a “Christmas special”, pinning its United Kingdom broadcast to December.

The trailer also showed Sherlock being a better-mannered person in his modern version while Watson is pretty much the same, with the exception of sporting a new mustache.

“Sherlock” co-creator Steven Moffat recently revealed the series fourth season will be finally begin filming Spring 2016, but before that fans will get a one-off special episode set in the Victorian era. This time, Sherlock appears in all his Victorian-clothed glory, hunting for clues with his faithful sidekick John Watson (Martin Freeman) and solving crimes the only way he knows how: through the power of deduction.

Keeping much of the plot under wraps, the 1.30minute trail shows the pair clatter through cobbled streets in horse-drawn carriages, running through spooky mansions and touches on Holmes’ brilliant, but insufferable nature.

Set apart from the continuity of the main show, the episode will be a stand-alone story with our heroes (played as usual by Benedict Cumberbatch and Martin Freeman) investigating a seemingly impossible case.

Cumberbatch opens the trailer saying: “The stage is set, the curtain rises… we are ready to begin”.

‘You’re Sherlock Holmes. Wear the damn hat’.

“Mark [Gatiss] will be starting very soon, he may have started”, Moffat said last week.

According to Digital Spy, the festive episode will arrive in cinemas near its television transmission and is not connected to Sherlock’s modern-day series. “That’s just the truth of it”, he explained further.
