1. This May Be The Show’s Last Season
Benedict Cumberbatch and Martin Freeman are such big stars now that it’s getting more and more difficult to confirm a fifth season for Sherlock.
Asked if there would be a Sherlock season five, Benedict said: “We never say never on the show. I’d love to revisit it, I’d love to keep revisiting it, I stand by that, but in the immediate future we all have things that we want to crack on with and we’ve made something very complete as it is, so I think we’ll just wait and see.
“The idea of never playing (Sherlock) again is really galling.”
2. There Will Be Three Episodes
Episode one, The Six Thatchers, was based loosely on Doyle’s short story The Adventure Of The Six Napoleons. The other episodes will be The Lying Detective, based on the story The Adventure Of The Dying Detective, and The Final Problem, after the book of the same name.
3. Season 4 is The Darkest One Yet
Expect some very grim times for the occupants of 221B Baker Street. “It’s a cliché to say it’s the darkest season, but it is,” says co-creator and writer Mark Gatiss, who also plays Sherlock’s brother Mycroft.
“It’s the darkest but also the most meaty, with the most proper dramatic incident we could possibly throw at them all.”
4. Watson and Mary Get A Baby
Last season it was revealed that Mary was pregnant, and season four will introduce Watson and Mary’s little bundle of joy. While the couple deals with the struggle of being new parents while sleuthing, Sherlock also learns to cope with the presence of baby Watson, with hilarious results.
5. … But Martin Freeman & Amanda Abbington Have Split In Real Life
Alas, while the Watsons are enjoying their new addition to the family, the actors playing John and Mary Watson (Martin Freeman) announced their breakup last year. They were in a relationship for 15 years, though they never married, and have a 10-year-old son, Joe, and an eight-year-old girl, Grace.
Amanda admitted it felt “weird” to film scenes with Martin with their on-screen baby, because “it was like when we first got together.” Heartbreaking.
6. Sherlock & Watson’s Bromance is Tested
The famous friendship between Sherlock and his faithful Watson takes on a different tone now that they are no longer flat mates in Baker Street. Now married, Watson is living with his wife Mary and their baby daughter. “Obviously when you get married and have a baby that trumps everything else in real life,” said Martin.
“But for this show John and Sherlock’s friendship has to stay central so it will still be very John and Sherlock-centric, but the reality is that John has moved on as he did in Conan Doyle’s books – he moved out and had his own life slightly away from that.
7. Sherlock Gets A Dog
The bloodhound stole the show in The Six Thatchers, with many fans commenting on how adorable he was and calling for him to be added to future episdoes.
Said Benedict of the pooch: “He was very sweet, but was a bit afraid of being in the centre of town, afraid of too many people and not great on hard surfaces. We were in Borough Market, with lots of people around, on concrete and tarmac. Cut to Amanda literally pulling a bloodhound around London, who was supposed to pull her around London. That was fun.”
8. There’s A New Villain
Sherlock may have concluded that Moriarty is dead, but there’s new baddie lurking in the shadows: Culverton Smith, played by Toby Jones.
“(Toby) does somehow, weirdly, give an impression of a genuine physical threat,” says Sherlock co-creator Steven Moffat. “There is something he can do, in his compact way, to create an extraordinary amount of menace.”
9. We May See A Third Holmes Brother
Sherlock creators Mark Gatiss and Steven Moffatt teased the word ‘Sherrinford’ before the premiere of season four, which excited fans because it’s the name Doyle had originally considered for Sherlock. Mycroft referred to a third Holmes brother in the last episode of series three, telling Sherlock: ““I’m not given to outbursts of brotherly compassion. You know what happened to the other one…”
Fans have assumed Sherrinford will be the name of Sherlock and Mycroft’s brother, but we shall have to see if that turns out to be true.
10. Sherlock Says ‘I Love You’
The famously indifferent and anti-social Sherlock gave fans a shock when he uttered those fateful words in the trailer for series four. We have so many questions about who Sherlock might be declaring his undying love for. Is it his long-time love, Irene Adler? His brother-in-arms Watson? His newfound furry companion?
One thing’s for sure, we wish Sherlock was saying it to us. We love you too, Sherlock…
