Many of the original Downton Abbey cast members are returning for this final chapter, including fan favourites like Hugh Bonneville as Lord Grantham, Elizabeth McGovern as Cora, Laura Carmichael as Lady Edith and Jim Carter as Mr. Carson. Michelle Dockery will take centre stage as Lady Mary Talbot, the eldest daughter of Lord Grantham.

Focus Features has released the first official trailer for Downton Abbey: The Grand Finale, the third and final film in the movie series based on the PBS period drama created by Julian Fellowes. The film hits theaters September 12.

But “When Mary finds herself in a public scandal and the family faces financial trouble, the household grapples with the threat of social disgrace. The Crawleys must embrace change with the next generation leading Downton Abbey into the future,” a synopsis of the movie reads.
