Katey Sagal Joins Fox's Best Medicine for Season 2

Katey Sagal has joined the cast of Fox's Best Medicine for its second season, according to Deadline. She has been added to the recurring cast. A recurring role means an actor returns episode after episode without being a full-time member of the main cast.

Sagal will play Kathleen Gavin, the estranged mother of Louisa. Louisa is played by Abigail Spencer. "Estranged" means the two have grown apart and are no longer close. Sagal's episodes will air later this season.

Best Medicine is an adaptation of the British series Doc Martin. An adaptation is a version of an existing show rebuilt for a different country, with new actors and often new locations. The show follows Martin Best, a surgeon who leaves his career in Boston to become a general practitioner, the family doctor who sees patients for everyday health needs. His new workplace is a village on the East Coast, where fishing is a central part of local life.

Liz Tuccillo is the showrunner of the series. A showrunner is the writer-producer who oversees the creative direction of a show, including its scripts and the team that makes them. Her name is the one that sits over the season's writing.

For viewers, the news is simple. A new actor is joining the second season in a role that will come and go across episodes, and Kathleen Gavin is the character whose arrival is now confirmed. Fans who want the full season schedule will need to wait for the broadcaster to announce air dates.

Casting announcements like this one often come months before a season reaches the screen, giving the production time to fit new characters into the story. Sagal's role is one of the first confirmed additions to the second season. The rest of the cast and the premiere date have not been detailed.
