Filming Begins on 'Downton Abbey' Movie as Imelda Staunton Joins Cast

Filming has kicked off on the highly anticipated feature film adaptation of period drama Downton Abbey.

Yes, it’s really happening. After all the rumors, false starts, and fervent fan hoping, production is under way, the movie was officially confirmed back in July. The major players we all know and love were confirmed to be returning, including Hugh Bonneville, Michelle Dockery and, of course, the indomitable Dame Maggie Smith. And now, principle photography on Downton: The Movie (which still doesn't have an actual title yet) is officially under way.

Plus, just when you thought this franchise couldn’t get cram anymore fantastic British women into its cast, Downton adds the great Imelda Staunton to its roster. Likely best known in America for her role as the monstrous Dolores Umbridge in the Harry Potter films, Staunton also happens to be married to a Downton regular, Jim Carter, who plays Carson.
