PASADENA, Calif. – The Crawleys are coming back, somehow.

The beloved upstairs/downstairs period drama "Downton Abbey," which aired on PBS from 2011-2016, continues its story as a feature film due in theaters Sept. 20.

Excited fans know next to nothing about what the lords, ladies and valets will be up to in the film. And the cast members aren't much help.

"I don’t even know what I can tell you," actress Laura Carmichael, who plays Edith Crawley, told reporters at the Television Critics Association Tuesday. "What can I remember has been released? There’s some new exciting people, which was dreamy. New cast members which you’ll love and enjoy."

Carmichael, who was promoting a role as yet another English noble in Starz's upcoming "The Spanish Princess," also promised the film will satisfy fans who have to buy a movie ticket to see the story.

"I think everyone will be pleased that we’ve upped the ante. Turned the volume up."

For the cast, "it was really magic to see each other and see each other become those characters again. Like seeing Jim (Carter) become Carson and seeing Phyllis (Logan) become Mrs. Hughes. It gave us all a thrill."

The actress has no idea whether this will mark the end of the "Downton" saga. "That is certainly a question for Lord Fellowes," she said, referring to series creator Julian Fellowes.

"I can’t speak for other people. But I can say we all had a dreamy time, it was lush."
