This is excellent news! Downton Abbey is one of those brilliantly trashy series that you feel smart watching because it's won Emmy Awards and half the characters have lovely upper-crust accents.
"I am extremely grateful to [British network] ITV for this," said the drama's creator and writer Julian Fellowes in a statement. "I have grown very fond of my Downton family and I certainly do not want to say goodbye to them quite yet."
Season three will follow super-posh English family the Crawleys — lead by the Earl of Grantham, Robert Crawley (Hugh Bonneville) — into the "roaring '20s", spanning the years 1920 to 1921.
Downton stars including Maggie Smith (who plays Violet), Michelle Dockery (Mary), Dan Stevens (cousin Matthew), Lisa McCune Joanne Froggatt (Anna) and Brendan Coyle (Bates) are confirmed to return.
In season two, which will premiere in Australia in 2012, the family is caught up in World War I and its aftermath (warning: be very careful reading about the second season on the internet, because there are huge plot spoilers everywhere).
