Shifting to 1923, six months after the end of series four, the two-hour ITV drama welcomes US actor Paul Giamatti to the cast, and is set in the summer during the height of the social season, where a scandal is brewing at Buckingham Palace.

Key events include a "coming out" party for debutante Lady Rose, which sees the family and servants travel to their London residence Grantham House, and the return of Cora's mother (Shirley MacLaine) and arrival of her brother (Giametti) from the US.

No hints of what the "scandal" threatening the Crawleys could be yet, but tragedy will be off the menu, as Downton executive producer Liz Trubridge assured TV & Satellite and viewers that (spoiler alert) we won't have any deaths like Matthew Crawley's shock demise last Christmas:

"It is packed full of story and it is without question the biggest episode we have ever done. It is the most spectacular, it's not set at Christmas and we won't be splitting up the family and the servants this time."

Watch a trailer, focusing on Lady Rose's coming out at Buckingham Palace, below:
