Downton Abbey: The Grand Finale trailer includes heartfelt tribute to Dame Maggie Smith

It's genuinely the end of Downton Abbey, with the Crawleys moving into the late 1930s and ready for their final bow.

With a trailer out today, Julian Fellowes' Downton Abbey: The Grand Finale takes the series' beloved characters further into the decade, following the early '30s glamour of the second film. The film will not only re-create London's West End, Ascot Racecourse, and other city sites in the '30s, but will also bring the characters back to where it all began, the titular mansion that started it all.
