Filming will begin next spring in Port Isaac with regular cast members Caroline Catz, Eileen Atkins, Ian McNeice, John Marquez and Jessica Ransom, also returning.
“I’m thrilled to be going back to the beautiful North Cornish coast to shoot series six of Doc Martin,” said Clunes.
“Our challenge this season will be to force Louisa and the doctor to live together with Baby James which as far as I can see has disaster written all over it…..And then there’s the dog and Dame Eileen but not necessarily in that order!”
The series has been recommissioned for ITV1 by Drama commissioning team Laura Mackie and Sally Haynes.
“Doc Martin is one of our most loved and valued dramas and I’m so pleased that we’re returning to Port Wenn to spend more time with the irascible Doctor, his family and patients,” said Mackie.
