In a new interview, Benedict Cumberbatch talks about why Sherlock series 3 will be a “treat” for fans.

When asked by Entertainment Weekly about the upcoming 3-part series, Cumberbatch told them, “It’s great. The second series was weird. Because it was such a phenomenal success, we were a bit distanced from the routine and the inhabiting of those characters.”

But with series 3, due for a premiere later this year in the United Kingdom, Cumberbatch and co-star Martin Freeman were prepared for what was to come.

“This season, straight into it, comfortable. And [the characters all] immediately fit under our skins. Really hard work because it wouldn’t be a good show unless we were trying to evolve it and set ourselves new challenges and standards. But I love it. I’m very fond of playing him. You’re in for a treat this series.”

EW pressed Cumberbatch for some teases about the season, but he decided no clue would be worth the sacrifice he’d be making. “Nothing that’s worth my liver or whatever part of my body they’d remove if I said anything.”

PBS has confirmed that Sherlock series 3 will premiere in early 2014 for United States fans. A specific release date for Europeans has not been revealed, but a commence point is expected to be announced once episode 3 finishes filming.

Episode 3, titled “His Last Vow,” is currently shooting in Cardiff. They are expected to wrap in early September.
