In what could be one of the most exciting reports that ever emerged regarding the filming of "Sherlock," it has been confirmed that production will start filming in Morocco very soon, though details on the report are very scarce.

According to Metro, the fourth season of the hit series will have some scenes filmed in Morocco. However, everything else is under wraps and it is unclear what will lead Benedict Cumberbatch's Sherlock and Martin Freeman's Dr. John Watson to the humid region.

Filming in Cardiff, Wales started in April and it has been reported earlier that the first episode has been completed, while the second is already under works. It appears that some of the scenes to be shot in Morocco will be part of either the third or fourth episode.

Another exciting confirmation is that of Toby Jones joining the cast as none other than the mysterious villain. Jones has starred in a number of British shows such as "The Secret Agent" and "Detectorists." He has also appeared on "Wayward Pines" and his voice was heard in several "Harry Potter" movies.

According to Deadline, series co-creator Steven Moffat said of Jones, "Delighted to have Toby Jones on board, bringing to life one of [Sir Arthur Conan] Doyle's finest villains." It has yet to be revealed which villain he will be but fans are ecstatic to see his antagonist at play.

While Cumberbatch and Freeman are obviously coming back to reprise their roles, it has been a hot rumor over the past months that Tom Hiddleston may crash into the cast to play the role of Sherrinford Holmes.

According to a March report by Unreality TV U.K., the buzz around Hiddleston's possible entry into the hit BBC series has been steaming over the past months. Creator Mark Gatiss said earlier this year that he would love to have the "Avengers" star on board.

However, due to Hiddleston's rather hectic schedule for 2016, it would be hard to get him on set if he ever does get tapped to play Sherlock's brother.

"Sherlock" season four is slated for release in January 2017.
