For fans of period drama Downton Abbey, the wait for series three has been excruciating – largely because we have heard so little about the plot and filming. However, one of the show’s producers has probably revealed more than she should in a new interview… This post contains spoilers.

Speaking to the Orlando Sentinel, CBS Masterpiece producer Rebecca Eaton teased future plot developments, new cast member Shirley MacLaine, and working with Dame Maggie Smith.

“There are some wonderful scenes between Maggie and Shirley MacLaine — Shirley MacLaine being as ditsy as ever,” Eaton said. “And Maggie barely restraining her sneer in having to deal with this American. Maggie Smith is a handful, it’s true. She’s very difficult. She knows her worth, and she’s tricky on the set, but she delivers when the time comes.”

Eaton supplied more teases: “Somebody will be born, and somebody will die, somebody pretty key in the cast, unfortunately not going to make it. It’s the 1920s now.”

One thing’s for sure, Eaton probably won’t be keeping her job for very long.

Who do you think will kick the bucket in the upcoming series? Could it be Maggie Smith, who is yet to sign for a future series, and seems to be difficult to work with–if this interview is anything to go by–? Sound off in the comments!
