Season four of the hit BBC television show "Sherlock" is said to grace our television screens once again in 2016. This is not surprising considering the fact that "Sherlock" seasons have always had a two year gap: the first season of "Sherlock" was shown back in 2010, the second season was shown in 2012 and the third season in 2014.

However, the 2016 "Sherlock" season four release rumor is now being refuted by BBC. Following BBC's denial, many have been led to speculate that audiences will be able to watch the fourth season sometime next year. During an interview with IGN, producer Steven Moffat said that he did not know when season four would be shown. Although Moffat is busy with the "Doctor Who" series, he assured fans that "Sherlock" will still be an A-1 TV series. He explained that Sherlock is like James Bond, adding that the show is full of excitement even if -- or perhaps because -- it is not shown regularly. 

Another rumor that is going around the vine is that season four will be preceded by a special episode. One thing is for sure though: "Sherlock" season four will be as exciting and appealing like the previous episodes.

The other problem given by Moffat is the availability of the cast. The movie careers of Benedict Cumberbatch and Martin Freeman are doing well, which is good for both actors. However, their busy schedule is also affecting the filming of "Sherlock." The two were cast together in the movie "Hobbit," which will be shown in cinemas this December. Cumberbatch is also included in the movie "Black Mass," replacing Guy Pearce as the brother of Johnny Depp.

"Sherlock" greatly increased the popularity of Benedict Cumberbatch, as his numerous fans, consisting mostly of females, were stirred by his performance as well as his unconventional appeal. The cast of BBC's "Sherlock" includes Benedict Cumberbatch, Martin Freeman, Jonathan Aris, Rupert Graves, Clive Mantle, Vinette Robinsons, Louise Brealey, Andrew Scott, Lars Mikkelsen, Jalaal Hartley and Una Stubbs.
