Downton Abbey ran for six seasons from 2010 to 2015 (though many argue it should have ended after three). The story continued with Downton Abbey: The Motion Picture in 2019, set in 1927—two years after the series finale—where the Crawleys and their staff thwart an assassination attempt on King George V. The 2022 sequel, Downton Abbey: A New Era, took a playful turn, featuring a film crew shooting at the estate, along with a glamorous detour to the South of France.

Now, the third and final installment, Downton Abbey: The Grand Finale, is set to wrap up the saga. Returning cast members include Paul Giamatti as Harold Levinson (Cora’s American brother), Dominic West, Elizabeth McGovern, Hugh Bonneville, Michelle Dockery, Laura Carmichael, Jim Carter, Phyllis Logan, Joanne Froggatt, and Penelope Wilton. Newcomers Joely Richardson, Alessandro Nivola, Simon Russell Beale, and Arty Froushan will also join the ensemble.

Notably absent from the announcement was Imelda Staunton, who played Maud Bagshaw in the previous films. Despite being married to Jim Carter (Mr. Carson), she confirmed the film’s existence in a BBC Radio 2 interview, quipping, “I don’t care” when asked about breaking any NDAs. Fans will surely miss her—and, of course, the irreplaceable Maggie Smith.

Written by Julian Fellowes and directed by Simon Curtis, the plot remains under wraps, but trailers hint at drama ahead. Set in the 1930s, the Crawleys face financial woes and a scandal involving Lady Mary, while the staff prepares for a new era as the next generation steps up.

Downton Abbey: The Grand Finale arrives in theaters on September 12—so get ready for one last visit to the beloved estate.
