The screenwriter has confirmed the upcoming sixth season of the period drama will be its last, but he already has a story in mind for a film version.

Speaking at the Chalke Valley History Festival in Wiltshire, England, he revealed, "I think I know what the spine of a story for a film would be. I think it would be fun, in a sense, because we'd be making it on a film budget. Ballrooms would be full, you could have crowds, you could have riots."
