Along with the Victorian era, "Sherlock" is headed to another unfamiliar place in the show's upcoming Christmas special -- movie theaters. Showrunner Steven Moffat announced Thursday at Comic-Con International in San Diego that the "Sherlock" Christmas special, set in the era of Sir Arthur Conan Doyle's original Holmes stories rather than the show's usual contemporary timeline, will get a theatrical release in select cities. This is similar to "Doctor Who" special "The Day of the Doctor" -- also executive produced by Moffat -- being shown concurrently in theaters with its initial BBC One broadcast in November 2013.
Additionally, PBS has released a trailer for the special. Deadline reports that Moffat said during the panel that the special should air in "the next year, we hope."
