But Benedict Cumberbatch revealed he might be enlivening the character a bit too well – admitting that he’s started to take on the detective’s abrupt and impatient nature.
The 40-year-old actor also joked that his actress mother Wanda Ventham thought he became ‘much curter’ with her during filming for the series.

Star of the show: Benedict Cumberbatch, 40, admitted his actress mother Wanda Ventham thought he became ‘much curter’ with her during filming for Sherlock
He told the Radio Times: ‘I do get affected by it. There’s a sense of being impatient. My mum says I’m much curter with her when I’m filming Sherlock.’
The London-born actor added that it was amazing to play a complex role, with Sherlock going through ‘very bleak’ moments as well as ‘funny’ ones since the show first aired in 2010.
And it seems Benedict’s mum isn’t afraid of showing some tough love to her actor son, as it was revealed she didn’t think he was ‘good-looking enough’ to play Sherlock.
Showrunner Steven Moffat told Time Out: ‘Benedict’s mum didn’t think he was good-looking enough to play Sherlock. Nobody did.

Nasty! The new season is said to be dark, nasty and meaty
‘He never thought of himself as good-looking and everyone casually agreed with him. He still regards it as preposterous that he’s become this sex symbol.’
Meanwhile, fans of the drama series will have to wait until New Year’s Day to watch the first episode of the new series.
It comes as the newest installment in the crime series is to be ‘the darkest and meatiest’ season yet.
Writer Mark Gatiss recently told The Telegraph that the show will feature ‘the most proper dramatic incident we could possibly throw at [the characters].’

Members of the cast have described the fourth series as ‘very sad’ and ‘nasty’ but also ‘magic’ and ‘the best yet’.
Eager fans of the show will be relieved to see it’s back having had to wait a year to the day since the last new episode aired.
As is the tradition with the series, the last episode aired on New Year’s Day this year, but was only a one-off special.
Before that, fans hadn’t seen new installments since 2014 when the third full season was on.

That began on January 1 2014 and was over by January 12, as it was only a three episode run.
The fourth season begins with episode one, which has been titled The Six Thatchers.
It will open with John and Mary Watson, played by real-life couple Martin and Amanda, who will welcome a new baby, Rosamund, into the family.
Fans have speculated that Mary will be killed off in the new series, following the same route as the Arther Conan Doyle books on which it is based.
On-set images from earlier in the year saw Benedict looking a little more ragged than usual, hinting that the character of Sherlock is to be put through the mill.
Whatever happens, season five has already been commissioned, and will continue the story over the next couple of years.
