The first trailer for “Downton Abbey: The Grand Finale” is finally here after weeks of teasers, and fans are already bracing for one last elegant ride. The film wraps up the beloved saga as the Crawleys navigate the 1930s. This time, Mary’s divorce is put on blast by the public just as she’s set to take over the Downton legacy and the family faces increasing issues with money putting Downton at risk. Creator Julian Fellowes, who’s written all three films, promises a proper sendoff. The movie will make its grand debut on September 12th.
