After his sinister role on The Handmaid's Tale, Josh Charles is switching gears to Fox's upcoming small town show Best Medicine, a remake of the British hit Doc Martin. The network released the official trailer for the series on Friday, December 12, which introduces Dr. Martin Best (Charles) as he moves from the big city of Boston to a small practice in Port Wenn. "I take people who are sick and I make them well," Martin explains in the sneak peek.
