BEVERLY HILLS, Calif., Aug. 2 (UPI) -- Writer-producer Steven Moffat says Sherlock fans will notice a difference from the titular sleuth's usual abrupt demeanor in the contemporary show's upcoming, Victorian-era special.
Sherlock is a modern-day mystery-drama inspired by Arthur Conan Doyle's late 19th/early 20th century stories. The TV series stars Benedict Cumberbatch as Sherlock Holmes and Martin Freeman as his sidekick, Dr. John Watson.
The special edition of the program will -- for the first time -- give a nod to the time period of its literary roots. How or why it will take place more than a century earlier than the series normally does will not be explained in the episode.
"Sherlock is a little more polished," Entertainment Weekly quoted Moffat as saying Saturday at a Television Critic's Association press event. "He operates like a Victorian gentleman, instead of a posh, rude man. He's a lot less brattish."
Meanwhile, Freeman's Dr. Watson will be "more uptight," Moffat revealed.
No U.S. air date for the special has been announced yet.
