Watson Season 2 Adds Robert Carlyle as Sherlock Holmes

Watson has found its Sherlock Holmes in Once Upon a Time‘s Robert Carlyle.

TV Line reports that Carlyle will have a recurring guest role in the investigative medical drama’s sophomore season. 

Watson, which premiered in January, started with Morris Chestnut’s Dr. John Watson grieving Sherlock, who died six months prior, and using the inheritance his friend left to open a medical clinic. The debut season wrapped up with Watson Season 1 Episode 13, “Your Life’s Work Part 2,” in May, which saw Watson and his team defeat Moriarty. 

As previously reported, CBS renewed the series for a second season in March. The network also announced that Watson will return with its sophomore season on Monday, October 13, at 10/9c. 

Watson Season 2 will see the ensemble “remain determined” as they “investigate and treat the world’s most rare diseases for their clinic’s patients,” per the logline.

“With his eyes fixed on the future, Watson faces an unexpected twist when Sherlock Holmes, who was presumed dead, resurfaces, forcing him to confront a buried secret from his past – one that lies hidden within his own body.”

“We are thrilled to have the mighty Robert Carlyle join the cast of Watson in Season 2,” executive producer and showrunner Craig Sweeny said in a statement, per Deadline.

“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 added.

“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,” Sweeny concluded. 

Watson Season 2 also stars Eve Harlow as Dr. Ingrid Derian, Peter Mark Kendall as Dr. Stephens Croft and Dr. Adam Croft, Ritchie Coster as Shinwell Johnson, Inga Schlingmann as Dr. Sasha Lubbock, and Rochelle Aytes as Dr. Mary Morstan.

Morris Chestnut, Larry Teng, Shäron Moalem MD, PhD, Aaron Kaplan, and Brian Morewitz executive produce Watson, and CBS Studios produces.
