The Good Life star Penelope Keith is returning to television in an adaptation of PD James's follow-up to Pride And Prejudice.
The actress will play Mr Darcy's aunt, Lady Catherine de Bourgh, in BBC1 show Death Comes To Pemberley, based on the bestseller, which features a murder mystery and is set six years after Jane Austen's original novel.
The cast will also include Doctor Who star Jenna-Louise Coleman, who will play Lydia Wickham, Trevor Eve and The Thick Of It star Rebecca Front.
Keith, who became a household name when she played snobbish Margo Leadbetter in The Good Life, also starred in The Norman Conquests and To The Manor Born.
The 1995 BBC version made a star of Colin Firth when he played Mr Darcy, famously emerging from a lake in a dripping wet shirt and breeches.
