Laura Carmichael is the latest addition to the cast of the Madame Bovary remake, according to reports.
The Downton Abbey actress, best known for playing Lady Edith in the hit ITV series, is to play a character called Henrietta in the upcoming period drama, Variety reported.
Prometheus actor Logan Marshall-Green is to join as the Marquis, and Olivier Gourmet will play Monsieur Roualt.
Mia Wasikowska is already set to star as protagonist Emma Bovary, a doctor's wife who has several affairs to escape her dull marriage, in Sophie Barthes' big-screen adaptation of Gustave Flaubert's 1856 novel. Sophie will direct from a screenplay she co-wrote with Rose Barrenche.
Ezra Miller will play Leon Dupuis, one of Emma's lovers, while Paul Giamatti has signed on to portray the town's local pharmacist Monsieur Homais. Rhys Ifans and Henry Lloyd-Hughes also have roles.
Madame Bovary will start filming in Normandy, France, on October 9.
Ezra, who has starred in The Perks Of Being A Wallflower and We Need To Talk About Kevin, has teased that the latest adaptation will be "dark and sexy".
"I'm very excited. There have been a lot of adaptations of the book before, but none of them are as dark and sexy as the book. With the director we've got and the cast, this might just hit it - the dark, sexy we are all crazy about," he said.
"I really anticipate a fantastic working experience and also a very wonderful film based on one of the greatest books ever," he added.
Madame Bovary would mark the second film role for Laura, who previously had a role in Tinker Tailor Soldier Spy.
