Downton Abbey: The Grand Finale Trailer Offers First Glimpse At Maggie Smith Tribute — Watch

Dame Maggie Smith is gone but not forgotten in the third (and final) Downton Abbey film.

Focus Features on Monday released the first trailer for Downton Abbey: The Grand Finale, which hits theaters Friday, Sept. 12. The footage sees Lady Mary Talbot (Michelle Dockery) stop and pause to look at a portrait of the late Dowager Countess Violet Crawley, who died in 2022's Downton Abbey: A New Era (prior to Smith's death in 2024).

Downton Abbey 3 "follows the Crawley family and their staff as they enter the 1930s," per the official synopsis. "As the beloved cast of characters navigates how to lead Downton Abbey into the future, they must embrace change and welcome a new chapter."

In addition to Dockery, returning cast members include Hugh Bonneville, Elizabeth McGovern, Laura Carmichael, Jim Carter, Phyllis Logan, Robert James-Collier, Joanne Froggatt, Allen Leech, Penelope Wilton, Lesley Nicol, Michael Fox, Raquel Cassidy, Brendan Coyle, Kevin Doyle, Harry Hadden-Paton, Sophie McShera and Douglas Reith.

Additionally, Dominic West (The Affair) is back as Guy Dexter, a character introduced in A New Era, while Paul Giamatti (Billions) reprises his role of Harold Levinson (aka Cora Grantham's brother).

New for the third film are Joely Richardson (Nip/Tuck), Alessandro Nivola (Doll & Em, The Many Saints of Newark), Simon Russell Beale (Penny Dreadful) and Arty Froushan (Carnival Row).
