ITV has released the first festive season-themed trailer for Downton Abbey's last ever episode.
The feature-length special, which will be broadcast on Christmas Day, hints at changes for the Crawley family and their loyal servants.
The trailer opens with the staff singing Auld Lang Syne as familiar faces flash across the screen.
Lord Grantham (played by Hugh Bonneville) is seen talking to his butler, Carson (Jim Carter).
"I hope you're not too unhappy about the way things have turned out," the aristocrat says.
"The world is a different place from the way it was, my lord, and Downton Abbey must change with it," Carson replies.
Henry Talbot (Matthew Goode) settles into the role of husband to Lady Mary (Michelle Dockery) and stepfather to little George.
Meanwhile, Lady Edith (Laura Carmichael) encounters Bertie Pelham (Harry Hadden-Paton) and the family and servants will apparently bid farewell to controversial figure, Thomas Barrow (Rob James-Collier).
"I arrived here as a boy, I leave as a man," he says to those assembled, as George begs him to stay.
The Dowager Countess, played by the scene-stealing Dame Maggie Smith, observes: "Every year we drink to the future, whatever it may bring."
A crowd raises a toast, but what they are toasting is not revealed.
"We never know what's coming, of course. Who does? But I'd say we have a good chance," Lord Grantham is heard to say.
Lily James reprises her role as Lady Rose Aldridge in the popular period drama created by Julian Fellowes.
Patricia Hodge, best known in recent years for her role in BBC One comedy Miranda, joins the cast as the mother of Bertie Pelham.
Matt Barber returns as Lady Rose's husband Atticus and Peter Egan is also back for the finale as Lady Rose's father, Hugh MacClare, Marquess of Flintshire.
The last ever episode promises fans love and loss, happiness and heartbreak.
As the family and servants prepare to welcome in 1926, they celebrate an unforgettable New Year's Eve together at the great house.
