Best Medicine Cast & Character Guide: Who Stars In Fox’s Medical Dramedy

Fox’s new show, Best Medicine, is a funny and heartwarming medical drama set in a charming small town on the Maine coast. The show features a talented cast of well-known actors. Best Medicine is based on the popular British series Doc Martin, which aired for 10 seasons and 79 episodes.

This story has been adapted for television in many countries, including France, Spain, Germany, and Russia. Each version centers around a surgeon from a major city who relocates to a small town and, after becoming afraid of blood, starts working as the local doctor.

It’s natural to compare the new show, Best Medicine, to other adaptations of the story. Fortunately, it starts with a strong premise and benefits from a talented cast who can bring the characters and world to life.
