A week or so ago I posted an all-too-brief teaser to the George Clooney “Downton Abbey” Christmas spot (a promo for the British charity Text Santa). Here’s the whole thing, in two parts (about nine minutes total); enjoy it in all of its gloriousness. (Particularly the Dowager Countess, swooning . . . and yet holding on to her hat.) “Downton Abbey,” minus Clooney, will be back January 4. Merry Christmas to all!
