Rebecca Front is joining the cast of season four of Poldark, which begins filming to week.
Front, who for me will always be The Thick of It’s Nicola Murray, is playing the “formidable mother” of lecherous cleric Osborne Whitworth.
Christian Brassington returns to play her son Osborne, the vicar with a foot fetish who will continue to torment his poor wife Morwenna (Ellise Chappell) in the next series.
Also back are Aidan Turner as Ross Poldark and Eleanor Tomlinson as his wife Demelza alongside Luke Norris and Gabriella Wilde who, as Dr Enys and his wife Caroline, will be “tested as never before” according to producers.
Harry Richardson and Tom York return as Demelza’s brothers Drake and Sam Carne, and Beatie Edney reprises her role as Prudie (although husband Jud remains absent).
Also back on the scene is Josh Whitehouse as Lieutenant Hugh Armitage, who remains deeply in love with Demelza.
The series run will have eight episodes – one fewer than series three – and will once again be adapted by Debbie Horsfield from the novels by Winston Graham and produced by Mammoth Screen.
The fourth series starts in 1797 and sees Ross having to defend Cornwall from an empowered George Warleggan (Jack Farthing).
Poldark is expected back on screen next summer.
