The Grand Finale. The intelligent noblewoman, played by Michelle Dockery, appears to have everything under control in the new trailer for the third and final Downton Abbey film. However, her status — and future ownership of the titular Yorkshire estate — is called into question when it’s revealed that she and her husband Henry Talbot (Matthew Goode) have gotten divorced.

Lady Mary Crawley is at the center of a new scandal in Downton Abbey: A Grand Finale.

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.
