HE’S BACK
It’s all hands on deck when Watson returns for a second season on Oct. 13.
The first episode of the new season finds Watson and the fellows springing back into action when Mary’s mother accidentally poisons herself while suffering from a rare form of dementia that is progressing with impossible speed.
Meanwhile, Sherlock Holmes resurfaces after being presumed dead.
Holmes will be played by Robert Carlyle, who joins the cast in a recurring guest role this season.
Carlyle’s Trainspotting cast mate Jonny Lee Miller famously inhabited the role for 7 seasons on CBS’ Elementary, where Watson showrunner Craig Sweeny worked as a writer and executive producer.
“We are thrilled to have the mighty Robert Carlyle join the cast of Watson in Season 2,” Sweeny said in a statement. “The man has played iconic roles in projects like Trainspotting, The Full Monty, and 28 Weeks Later… and now he steps into the shoes of the most iconic detective of all, Sherlock Holmes.”
Sweeny also shared more on Holmes’ return this season with the following tease: When Watson’s best friend and former partner makes a shocking reappearance in his life, Watson is forced to confront their shared past — and a secret that may lie buried within Watson’s own body.
It looks like Holmes has chosen just the right moment for a homecoming.
In addition to series lead Morris Chestnut as John Watson, returning for Season 2 are cast staples Eve Harlow (Dr. Ingrid Derian), Peter Mark Kendall (Dr. Stephens Croft and Dr. Adam Croft), Ritchie Coster (Shinwell Johnson), Inga Schlingmann (Dr. Sasha Lubbock), and Rochelle Aytes (Mary Watson).
The “A Son in the Oven” Season 2 premiere episode of Watson airs Monday, Oct. 13 (10:00-11:00 PM, ET/PT) on the CBS Television Network, and streaming on Paramount+ the day after the episode airs.
