WATCH: 'Downton Abbey' Moves with the Times in First Film Trailer

We've already read reports that the first Downton Abbey movie trailer teases a royal visit, but now we can finally watch it for ourselves.

The two-and-a-half minute trailer has just arrived online and introduces us to new characters including King George V's formidable-looking butler, played by David Haig (Bill from Killing Eve's first season. RIP.)

We also get a glimpse of Imelda Staunton (Harry Potter, Vera Drake) as another new character, Lady Bagshaw, who doesn't seem to see eye to eye with Dame Maggie Smith's Dowager Countess.

When Hugh Bonneville's Lord Grantham urges his mother not to argue with Staunton's Lady Bagshaw, the Dowager Countess fires back one of her trademark one-liners: "I never argue, I explain."

Check out the trailer below.

We already knew that the trailer would show Lady Mary (Michelle Dockery) asking Carson (Jim Carter), the family's beloved former butler, to come out of retirement for the royal visit. But we didn't know it would introduce a possible love interest for Allen Leech's Tom Branson or show us the fiery side of Lesley Nicol's Mrs Patmore, which is always fun to see.

Joanne Froggatt, who plays Lady Mary's maid and confidante Anna Bates, recently described the film as an "elevated" version of the TV series, which the trailer seems to confirm: the Grantham Family may be adjusting to modern life with such newfangled novelties as a "buffet supper," but somehow the house itself looks even more lavish than we remembered it.

The Downton Abbey movie opens in the U.K. on September 13 and then in U.S. theaters on September 20.
