It’s been over a year since Sherlock Season 4 concluded. Since that time, there’s been no official word on the possibility of a fifth season, but that hasn’t stopped literally everyone from speculating, or asking the cast and producers about it every time they get the chance.
Now, at this point it seems kind of obvious that if a fifth season of Sherlock happens, it won’t be any time soon. Not only does the end of Season 4 work as potential series finale should the folks in charge decide to take a break that lasts longer than the series’ usual hiatus periods, but everyone’s schedules so incredibly packed it’s hard to know when they’d even film.
Stars Benedict Cumberbatch and Martin Freeman are involved with multiple other projects. They’re both part of the Marvel Cinematic Universe now, with Freeman recently appearing in Black Panther and Cumberbatch popping up in the just-released Avengers: Infinity War. Cumberbatch’s latest series Patrick Melrose will drop on Showtime this spring, and Freeman’s zombie film Cargo just debuted at the Tribeca Film Festival. Even co-creators Steven Moffat and Mark Gatiss seem busy with other things, most notably their slightly bizarre-sounding new adaptation of Dracula.
To put it kind of bluntly: No one really has time for a trip back to 221b Baker Street. Moreover, it’s not entirely clear that anybody wants to do so, anytime soon.
