'Downton Abbey' teases final season with emotional first look

"Downton Abbey" is giving fans a glimpse of its sixth and final season in a new trailer, and it's a tearjerker.

Britain's ITV released a promo for the period drama on Saturday, and the video has already been viewed more than 370,000 times on YouTube.

Filled with sad music, the one minute clip begins with Robert Crawley, Earl of Grantham (Hugh Bonneville) telling Mr. Carson (Jim Carter), "If I could stop history in its tracks, maybe I would. But I can't, Carson, for neither you nor I can hold back time."

The promo goes on to show Lady Edith Crawley (Laura Carmichael) smiling as she appears to finally find love again, while long-suffering Anna Bates (Joanne Froggatt) sheds more tears.

The show premiered in 2010, and over the course of its five seasons has become a fan favorite and the most-nominated international series in the history of the Emmy Awards.
