"Downton Abbey" tides fans over the season 5 premiere with some new photos. Posted on the show's official Instagram page, the pictures give first look at two new additions to the cast ensemble.
They are twins Oliver Barker and Zac Barker, who will play Master George Crawley, as well as Fifi Hart, who will portray Miss Sybbie Branson. George is the son of Lady Mary and the late Matthew Crawley, while Sybbie is the daughter of Tom Branson and his late wife Lady Sybil. Both of these children were still babies when viewers last saw them in season 4.
Filming for the new season of "Downton Abbey" is currently underway. The show returns January 4, 2015 at 9 P.M. ET/PT on PBS, months after it airs in the U.K.
