IMDB now has details of the full cast list for the BBC's upcoming Sense and Sensibility, due to air this Autumn.
Elinor Dashwood - Hattie Morahan
Marianne Dashwood - Charity Wakefield
Mrs Dashwood - Janet McTeer
Margaret Dashwood - Lucy Boynton
John Dashwood - Mark Gatiss
Fanny Dashwood - Claire Skinner
Mrs Ferrars - Jean Marsh
Edward Ferrars - Dan Stevens
Willoughby - Dominic Cooper
Colonel Brandon - David Morrissey
Sir John Middleton - Mark Williams
Mrs Jennings - Linda Bassett
Miss Steele - Daisy Haggard
Mr Harris (the doctor) - Damien Thomas
I am presuming that 'Miss Steele' is Lucy, and not her sister, and notably there is no casting mentioned yet for the Palmers, Lady Middleton or Robert Ferrars.
Overall this looks a relatively strong cast. I don't know of either actress taking on Elinor and Marianne. I am most interested in seeing Dan Stevens as Edward Ferrars - excellent casting there I think - and although David Morrissey does not stand out for me as an ideal Colonel Brandon, he is an actor I have huge respect for, and can imagine him making any role his own. I also enjoy Mark Williams, and think he'll bring a pleasantly comedic edge to John Middleton.
In other details, we learn this series will be a three-parter (180 mins) and is being directed by John Alexander whose trade has been plied almost exclusively in TV, including two Series One episodes of the BBC's hit series Life on Mars. Andrew Davies is penning the screenplay, amidst claims that this will be the 'sexed-up' version of Sense and Sensibility. Of course we always get this familiar little dance before any Davies adaptation, which almost always ends up being very chaste and sweet, a far cry from the frenzied sex-fest we are always being promised (unfortunately).
