Fox’s midseason series "Best Medicine" is based on the beloved British show "Doc Martin". The show’s latest casting will make the connection even more concrete.

Martin Clunes, who played the title character on "Doc Martin", has signed on for a guest role in "Best Medicine" — though not as the British doctor he played for 10 seasons spanning almost 20 years. Instead, Clunes will play Dr. Robert Best, the father of lead character Dr. Martin Best (Josh Charles).

TV Insider has learned that Martin Clunes will be back as the father of Josh Charles‘ Dr. Martin Best in "Best Medicine" Season 2.

“He’s going to be sort of, I think, hopefully trapped in an uncomfortable evening with a bunch of crazy townspeople. But at the same time, he will be going through his own troubles. So, he will be a little off balance, but of course, he won’t admit to it,” showrunner Liz Tuccillo told TV Insider on the set of the cozy dramedy about his return.

“And then at the end of the day, he and Martin will go even a little bit deeper with their relationship and with the past and with Rosemary, the sister that passed away. So, it’ll be an opportunity to go to have much more hilarity with Martin Clunes, but also to go sort of deeper emotionally.”
