Tantalising glimpse of Aidan Turner during filming of Poldark Series 3

Poldark filming

First-look video footage from the set of Poldark shows a glimpse of Aidan Turner riding across the Cornish cliffs.

Filming has been under way since September and exclusive drone footage shows Turner in character as Ross Poldark on his trusty steed Seamus.

The popular BBC One show will be back for a third series in 2017, although no air date has yet been confirmed.

Eleanor Tomlinson will return as Demelza, and three new characters will be introduced - played by Doctor Thorne star Harry Richardson, Tom York of Olympus fame and New Blood's Ellise Chappell.

York and Richardson will play Demelza's brothers, Drake and Sam, while Chappell will star as Morwenna, cousin to the character Elizabeth Poldark, played by Heida Reed.

The series is produced by Mammoth Screen, and writer Debbie Horsfield has penned nine new episodes of the 18th century Cornish drama, which is based on the books by Winston Graham.

Horsfield said: "We're thrilled to be kicking off Series 3 with a fantastic array of new characters and a story which scales new heights of conflict, feuding, passion and drama.

"Ross is older but not necessarily wiser, and his recklessness sometimes costs him, and his loved ones, dear. We're in for a rollercoaster ride where the stakes have never been higher."

The series has been filmed in Cornwall and Bristol, as well as in Bristol-based Bottle Yard Studios.
