Benedict Cumberbatch, the star of BBC's Sherlock, recently admitted that he still finds himself "bemused" by the success of the show.

Cumberbatch, who plays the titular Sherlock Holmes on the popular British series, said that he was ultimately shocked by the overnight success.

"None of us had any idea about what kind of success we would have on our hands, and it shocked all of us," Cumberbatch told Vulture recently. "That first night it aired in England, my God, I wasn't really aware of this internet-TV culture, because I hadn't really dabbled in a series or something with a potential cult following, like a Doctor Who or Downton Abbey or anything like that.

"When this sort of live, immediate, audience-internet reaction [to Sherlock] exploded, it was like being in a theater of millions of people. It was so immediate, the response, that it was sort of terrifying. And this thing of trending on Twitter - I didn't really know what Twitter was until that night. That first sort of dawning of Oh, God, this is what we're getting involved with was extraordinary. And I mean, it still bemuses me."

Sherlock has continued to grow in popularity in the U.K., the U.S. and all over the world, especially considering its presence on Netflix Watch Instantly.

Cumberbatch is finding great success in the movies as well, having portrayed mathematical genius Alan Turing in The Imitation Game, for which he is receiving Oscar buzz. Both Turing and Sherlock Holmes are shown to be socially awkward in spite of their technical genius, but the actor does not think it is as simple as them being autistic.

"I don't think it's that simple," he said, when asked if either character was on the spectrum. "Possibly Sherlock is. Sherlock's a sociopath, and I think both of them are utterly conditioned by their circumstance."

Fans and critics alike have fallen in love with Cumberbatch's portrayal of Sherlock in the series of the same name. In fact, the actor received his first Emmy for the role back in August.

Sherlock is slated to return for a one-off holiday special at the end of 2015. It will then return for the three-episode fourth season in early 2016.
