In the pictures, George and Hugh – who plays Lord Grantham - can be seen playing around with a director's clapper board on the festive-looking parlour set at Downton Abbey.
We can't wait!
So far, no details about George's role in the Downton Abbey sketch have been revealed, but judging from his clothing in the preview pictures, we're imaging he's likely to be a guest of Lord Grantham's, rather than anyone downstairs.
However, actress Laura Carmichael – who plays Lady Edith – did let slip during a recent interview that George's character tries to plant a kiss on the Dowager Countess, played by Dame Maggie Smith.
There's a very brilliant moment with Maggie and George, I don't know if I want to give away any more than that really. but George wants a kiss and Maggie ends up on the floor, it's wonderful," she told ITV's This Morning.
Laura also revealed the cast were totally starstruck by George's appearance and didn't really believe it would happen until he was actually there.
It's believed George's appearance stemmed from the friendship he developed with Hugh on the set of film The Monuments Men.
