Who plays Doctor Martin Ellingham in the British television show 'Doc Martin'?

I enjoy watching the Doc Martin series. The character might be grumpy, but he's a brilliant Doctor and always has time for people. I wish that was the case for real. I think it still is in less populated areas of Britain. The area where the show is set is really beautiful.

grumpy doc Martin. never actually had the chance to watch it, maybe I should!
