Back in May, we reported that the Season 4 Premiere of Downton Abbey will air January 4 on PBS, the first of eight all new episodes that will run through February 23. Today, the network has debuted the first trailer with footage from this critically-acclaimed series created by Julian Fellowes (Gosford Park). Shirley MacLaine returns as Martha Levinson, along with several new actors, including Tom Cullen, Nigel Harman, Dame Harriet Walter, Joanna David, Julian Ovenden, Dame Kiri Te Kanawa and Gary Carr. They will join Hugh Bonneville, Elizabeth McGovern, Maggie Smith, Michelle Dockery, Jim Carter, Joanne Frogatt, Brendan Coyle, and the rest of the large and beloved Downton Abbey "family." Take a look at the first footage from the highly-anticipated Season 4 before it debuts next year.
