BBC teases Season 4 of Sherlock, promising there will not only be three new episodes but a “special” as well.
As of now, no date has been announced though producers have announced to begin filming in January and are speculating for a late 2015 release.
The busy schedules of Benedict Cumberbatch and Martin Freeman may delay Sherlock’s Season 4 premiere release. Cumberbatch is currently working on his character, Smaug the Dragon, for the Hobbit trilogy. In addition to the Hobbit, Cumberbatch may take on another character for another movie. Sherlock‘s producer is not worried about the possible schedule conflicts with his actors and tells reporters that they will do what they can without sacrificing the quality of the show.
