Just yesterday we reported that the third season of BBC's Sherlock would start shooting next week. At the time I expressed how much I would love to see the series continue past season 3, and I'm incredibly excited to report that series star Benedict Cumberbatch has confirmed that there will indeed be a fourth season, and maybe even a fifth! The Radio Times talked to the actor recently and this is what he had to say about it!
We've agreed to two more series but I could get into trouble for saying that. All I know at the moment is I'm doing these three [episodes for Series 3] and another three [episodes for Series 4].
When asked about a possible fifth season the actor said,
It just depends on Martin [Freeman} and I's availability, how long we can keep it going. It depends on Steven [Moffat]'s ability. I'd love to keep it going.
So it seems like they would like to keep it going if they could! It all comes down to time and availability.
