Prepare for one of the most gripping finales on television ever.

'Downton Abbey' Star Has 'Tears, Tears, Tears' On Her Last Day On Set

On Wednesday, Vanity Fair reported that the final episode of Downton Abbey, which will likely air in spring 2016, is making everyone break down in tears. Executive producer Gareth Neame said at the Edinburgh TV Festival that not only did the actors let their tears fall, but there were "four middle-aged men trying not to cry in front of each other."

So what is it that's happening in the episodes that's causing everyone to cry? Naturally, no one could give specifics, but it seems like the last moments might be happy rather than sad.

Could 'Downton Abbey' Return In 40 Years?

"I am not going to give a spoiler," Jim Carter, who plays Carson on the series, said. "But these characters, we say goodbye to them, but it's not final...we see them setting off on different paths."

Carter added that the ending is "really satisfying" and people will need "two hankies on Christmas night."

Meanwhile, Joanne Froggatt, who plays Anna, recently told Deadline that audiences will find out what happened with the suspicious death of Mr. Green.

"We do see the mystery behind Mr. Green's resolved," Froggatt said. "Obviously how it's resolved I can't tell you, or whether it's good or bad for the Bates I can't tell you, but it's resolved. We get to the bottom with what exactly happened, and as always, there's quite a lot of drama for Anna and Mr. Bates in season six."

Downton Abbey Season 6 premieres in the United States on Sunday, January 3.
