Early this morning the official “Downton Abbey” Twitter account sent out a photo of a butler holding a silver platter with a card reading: “We cordially invite you to return to Downton Abbey — Only in Cinemas.”

It’s a sequel to the worldwide TV hit, but the catch is that it will be a feature film made for release in movie theaters.

“The original main cast from the hit series are returning, and shooting starts in September,” Variety reports, adding: “Many of the stars of the series had spoken of their eagerness to return for a big-screen ‘Downton,’ and the producers said Friday the original principal cast are on board the movie.”

The report notes that Michelle Dockery, Maggie Smith and Hugh Bonneville are among the cast members who will be a part of the project.

“The movie will be a Carnival Films production, with Focus Features and Universal Pictures International distributing,” Variety notes. “Julian Fellowes, who created the period drama, has written the screenplay and will produce the feature. Brian Percival, who directed the original series’ pilot, will direct the film.”

Variety adds: “The series garnered numerous awards including a trio of Golden Globe Awards, 15 Primetime Emmy Awards, and a Special BAFTA award. With 69 nominations, it was the most nominated non-U.S. television show in the history of the Emmys.”
