BBC One confirmed Sherlock's 2015 filming starts in January.
News leaked and the BBC released an official statement about the upcoming season in "Sherlock: Fourth series to follow a special in 2015." Filming will begin in January 2015 and be shown soon after. Co-creator Mark Gatiss promised story lines where Sherlock and Watson fall "into deeper and darker waters."
Some of the surprise was taken away from the announcement when Martin Freeman, who plays John Watson, told the Telegraph off record "a Christmas special" seemed to be in the works.
Which makes sense as Steven Moffat uses the same format for Doctor Who. Since Sherlock’s become a media buzz word, the network and creators seem to be taking advantage of the popularity.
And if you thought the return of a "dead" Sherlock (Benedict Cumberbatch) in Season 3 was a big deal, Moffat says to just wait because "we're reasonably confident that the very next thing to happen to Sherlock and John, is the very last thing you'd expect."
One of the signature styles of the Coupling creator tends to revolve around a shocking, explosive beginning. That's one reason everyone is so excited for Who to return in August. Expect the unexpected always seems to hit home with the enigmatic first season of any doctor.
Moffat and Gatiss' show started in 2010 with each episode lasting 90 minutes. Seasons are each only three episodes and last less than a month without specials.
So why the long wait between seasons?
Charlotte Moore, BBC One's controller, said it all came down to availability. Moffat and Gatniss working on Who and Sherlock means pre-production time is limited. The hit show launched Cumberbatch and Freeman into the media stratosphere and into Hollywood demand.
Cumberbatch will be appearing in The Imitation Game. He stars as Alan Turing, a World War II code breaker who managed to help crack Nazi Germany's Enigma code. Turning was later criminally prosecuted for homosexuality.
Based on Andrew Hodges's biography Alan Turing: The Enigma, Morten Tyldum's directing the feature while both The Weinstein Company and Studio Canal will distribute the film. Expected release date is November 21 and also stars Keira Knightley and Matthew Goode.
Interestingly, Freeman has been appearing on FX's recent television drama Fargo, set in the same universe of the 1996 movie by the Coen brothers. However, the show takes place in 2006 while the movie was set in 1987. The first season also starred Billy Bob Thornton, Allison Tolman, and Colin Hanks. Freeman played Nester Nygaard, a man seduced by the dark power of murder that Lester Malvo (Thornton) offered. The malevolent character is a 180-degree flip to everything John Watson represents.
Hartwood Films, Sherlock’s production company, are happy to have the team of men back. “There was unanimous goodwill to make this work so we're thrilled that 221b is going to be inhabited again."
Sherlockians and Holmesians, are you ready?
