The 2 1/2-minute preview shows Robert and Cora Crawley (Hugh Bonneville and Elizabeth McGovern) preparing to hand over their palatial British country estate to their elder daughter Mary (Michelle Dockery), whose divorce is making her a pariah in social circles.

The Grand Finale has dropped, but it has divided diehard fans, with some even fuming about one character's exit and what it could mean for Downton's future

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.
