It has been the fear of fans of Sherlock that the show itself could finally come to an end with each series. The simply truth is, both Benedict Cumberbatch and Martin Freeman are rather big time Hollywood film actors as well as in the theatre for Cumberbatch. With both having signed to work with MARVEL, Freeman has already starred in Avengers: Civil War and Cumberbatch will take the lead role in upcoming MARVEL film ‘Doctor Strange’, the reality is that both actors no longer have the need or the time to carry on making Sherlock.
Steven Moffat in an interview with The Telegraph admits that he is not sure if there will be another series of Sherlock after Series 4:
“I don’t know how long we can keep it going. I’m personally willing but I’m hardly the main draw. I would be moderately surprised if this was the last time we ever made this show. But it absolutely could be. We do have two film stars in the program. They haven’t needed to do these jobs for a very long time. They’re coming back because they want to.
I’m amazed that we’ve got this far. I thought that once they had become extremely successful, we would only get to do one more series. There’s never going to come a time when we do a longer run, because this is what the series has become. It’s an occasional treat where you get three movies. It’s how it works.”
The very fact that both lead actors are willing to continue, for now, with Sherlock is a testament to their love of the characters, show and the fans. We have seen the characters of Sherlock and Dr Watson come together and have had some brilliant adventures, if Series 4 did become the very last series for them both, no fan would begrudge them that after their success on the big screen.
