'Downton Abbey' Christmas Special Teaser: Beware Of Season 4 Spoilers

"Downton Abbey" specials wait for no American viewers. Even though the UK show's fourth season hasn't aired in the US yet, the two-hour Christmas special, capping off the season, is just around the corner for British viewers.

The special will air on the UK's ITV on Dec. 25 and in this teaser, we get a glimpse of what's to come. Shirley MacLaine is back as Cora's mother, and we see Paul Giamatti as her brother.

Season 4 won't begin airing in America until Jan. 5, 2014 as part of Masterpiece on PBS, and the Christmas special won't air until after that. Die-hard fans who don't want ANY Season 4 spoilers should beware of this teaser. It's not terribly revealing, but tread lightly!
