‘Downton Abbey’ Christmas Special Teaser: Shirley MacLaine and Paul Giamatti Are Neither Holly Nor Jolly (Video)

Pass the smelling salts; tensions are rising between Cora and Violet

Christmas is coming to “Downton Abbey,” but it’s not all pudding and carols. As a new teaser for the series’ Christmas special reveals, Shirley MacLaine and Maggie Smith are ringing in the Yuletide by knocking heads.

The teaser gets off to a frosty start, with MacLaine — playing Cora’s American mother — declaring, “Well, the gang’s all here, I see.”

“Is that American for hello?” Smith’s Violet Crawley haughtily replies.

Happy holidays, everyone.
