'Sherlock' Creators Have 'Plotted Out' Fourth and Fifth Seasons

Although the U.S. premiere of Sherlock's third season is still more than two weeks away, co-creator Steven Moffat has seemingly confirmed that Holmes and Watson will be back for a fourth -- and he even dangled the possibility of a fifth.

"Rather excitingly, Mark [Gatiss]and I, for no particular reason, just started plotting out what we could do in the future,” he told reporters at a Wednesday screening of the Season 3 finale, which airs Sunday in the United Kingdom. “We plotted out the whole of series four and five. The ideas we had that day, I thought were the best we’ve ever had.”

The Independent reports that Moffat continued, "So we have got plans – but our plans don’t tend to be ‘Let’s blow up the world or cast the most famous person in the world," they tend to be ‘What exciting twists and turns can we add to this?’ and I think we’ve got some crackers!”

The fourth season isn't exactly a surprise: Benedict Cumberbatch revealed in March that he and co-star Martin Freeman had agreed to two more seasons. When asked about continuing beyond that, the actor said, "It just depends on Martin and I’s availability, how long we can keep it going. It depends on Steven’s ability. I’d love to keep it going.”

BBC One would undoubtedly love it, too, as the Season 3 premiere scored series-high ratings.

The new season of Sherlock premieres Jan. 19 in the United States on PBS.
