Morris Chestnut and Randall Park Talk 'Watson' Season Finale: “It All Comes to a Head”
MILWAUKEE (CBS 58) -- The season finale of the CBS hit show 'Watson' is this weekend. CBS 58's Alex Corradetti spoke with Morris Chestnut and Randall Park, two stars on the show about what viewers can expect in the thrilling conclusion.
The gripping two-part season finale of 'Watson'—the CBS original series reimagining the Sherlock Holmes universe—comes to a close this weekend, and fans are in for a wild ride.
“It’s a take on the Sherlock Holmes mythology where Sherlock gives Watson a medical clinic to solve rare medical mysteries,” Chestnut explained. “Of course, we can’t leave the bad behind, because we have the villainous James Moriarty, brilliantly played by Randall Park.”
For Park, stepping into the role of Moriarty was an unexpected but exciting challenge. Known for his comedic roles, Park relished the chance to play a character who seems like an ordinary, kind man on the surface—but hides something much darker underneath.
“He’s supposed to throw you off a little bit,” Park shared. “It was really fun because I rarely get to play these kinds of characters.”
The finale picks up after a dramatic cliffhanger. “The first part left us with two twin doctors, both very ill, and I only have enough medicine to save one of them,” Chestnut said. “Watson has to flip a coin given to him by Sherlock Holmes to decide which twin to save. Meanwhile, Moriarty’s wandering the hospital, tormenting everyone. It all leads to a face-to-face showdown.”
Beyond the action and suspense, both actors praised the emotional depth of the storylines. “Reading some of the comments, audiences really care for these characters,” Chestnut said. “We’re really rooting for them—and also rooting for the demise of the person responsible, which is Moriarty.”
The series also explores deeper themes of science and ethics. Park explained how Watson’s collection of DNA for the good of humanity falls into the wrong hands—turning it into a weapon with global consequences.
Throughout filming, the actors say their on-screen chemistry extended behind the scenes. “I love working with Randall,” Chestnut said. “He’s such a nice guy off-camera, and then in character, I’m looking at him like, ‘Is this dude serious?’ It was incredible.”
Park echoed the sentiment. “I’ve been a fan of Morris Chestnut for a very long time. Meeting him was an honor—and working with him, especially playing this charged dynamic, was so much fun.”
The second part of the Watson season finale airs Sunday at 8 p.m. on CBS 58.
