The world doesn't stop turning, even at "Downton Abbey."
The venerable estate may still keep to many of the old ways, but as ever-correct butler Carson (Jim Carter) intones in this 20-second teaser for Season 5, "I feel a shaking of the ground I stand on."
Change has already come to the Abbey, and began moving at a faster pace last season as Lady Mary (Michelle Dockery) and brother-in-law Tom Branson (Allen Leech) began a mission to modernize the estate's farming practices.
But as Carson says, even more change is coming, so what might we expect in the next season of "Downton Abbey"? There are new characters, of course, including the Dowager Countess' new maid (Sue Johnston), art historian Simon Bricker (Richard E. Grant), and Lady Anstruther (Anna Chancellor), who was Jimmy's former employer.
There will be new romances, or at least, continuation of previous ones. Lady Mary will likely choose betwen her two suitors, Lord Gillingham and Charles Blake. Meanwhile, we wouldn't be surprised to see Tom's relationship with schoolteacher Sarah Bunting.
"Downton Abbey" season 5 debuts in the U.K. this fall. The PBS premiere date in the U.S. is still undecided.
