Daniel Dae Kim will have a recurring role on "The Good Doctor."
Kim will play Dr. Jackson Han, a brash new chief of surgery at St. Bonaventure Hospital.
The character makes a big splash and puts Dr. Shaun Murphy's (Freddie Highmore) career in jeopardy.
"As a fan of our show, I'm thrilled to be doing a guest arc with such a talented, kind and hard-working cast," Kim said in a statement.
"It's an added bonus for my character to be directed by our own Freddie Highmore, who's proving to be as talented behind the camera as in front of it," he added.
"It's been a lot of fun already and I'm excited for the episodes to air."
"The Good Doctor" is based on the South Korean series of the same name.
Kim was instrumental in bringing the show to the U.S., and executive produces via his 3AD production company.
Kim is known for playing Jin-Soo Kwon on "Lost" and Chin Ho Kelly on "Hawaii Five-0."
"The Good Doctor" marks his first TV role since leaving "Hawaii Five-0" in 2017.
