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).
