British actress Sienna Miller is stepping back in time to star in a period comedy based on JANE AUSTEN's novel Lady Susan.

The Alfie star has been cast as the leading lady in Love And Friendship, about a scheming widow who embarks on a search for suitable husbands for herself and her daughter.

Chloe Sevigny will co-star in the film, which will be directed by Whit Stillman.

Production on the project is due to begin in the Irish countryside this summer (14).
