Benedict Cumberbatch and Martin Freeman are returning to the roles of Holmes and Watson for a new Sherlock special - though unlike anything fans of the show have seen before.
It was revealed earlier this year that the BBC show would be returning in a Victorian-era set one-off episode.
The first footage debuted today at the show's Comic-Con panel in San Diego.
The 90 second clip shows Cumberbatch in a deerstalker smoking a pipe, while Freeman sports a moustache as Dr. Watson.
