The BBC has not made any official announcements regarding the Sherlock Season 4 release date, but actor Martin Freeman, who plays Dr. Watson on the series, has shared some information about when fans can expect new episodes. While on the British chat show The Graham Norton Show, Freeman stated: “We are back filming now and the three shows will, I imagine, be out around Christmas.”
Season 3 ended with the supposed return of Moriarty. Co-creator Mark Gatiss told Entertainment Weekly about how Moriarty’s return will impact the characters. “All I can say is, this is a major, life-changing series for the regulars," said Gatiss. "The repercussions of Moriarty’s apparent return are far-reaching. It’s very big stuff.”
Very little has been revealed about Season 4 but Masterpiece has noted that the fourth season “begins with the mercurial Sherlock Holmes, back once more on British soil as Doctor Watson (Martin Freeman) and his wife Mary (Amanda Abbington) prepare for their biggest challenge yet: becoming parents.”
Speaking of baby Watson, Abbington revealed in an interview with Vulture what kind of parents John and Mary would be. "On the one hand, they’d probably be reckless because they’re both quite psychopathic," said Abbington. "But I think an assassin and an army doctor who loves trouble, I mean, that kid has got nothing to worry about. Screwed up mentally, of course, but if there’s any bullying on the playground, we’re covered."
Fans have waited two years to see a new episode, excluding the one-off episode that released earlier this year, and the new season promises to not disappoint.
