NeW YORK, Sept. 12 (UPI) -- Downton Abbey icon Hugh Bonneville says he has been honored to work on a series that has so significantly impacted the cultural zeitgeist.

In theaters on Friday, Downton Abbey: The Grand Finale is billed as the last chapter in a 15-year franchise that includes a beloved, Emmy-winning six-season costume drama and three movie sequels.

It follows the wealthy Crawley family and the loyal servants who work for them at their British country estate from 1912 to 1930.

"It's a great and unique gift," Bonneville told UPI in a recent Zoom interview.

"For all these years, we have been in people's homes and now in people's movie theaters and I urge people to go to the movies to see it, because the Downton family is huge now and to share this final outing with your fellow family members is a real, real treat."
