Its official: "Downton Abbey" has wrapped its final episode.

The series held a press screening at the May Fair Hotel in London, where the cast revealed it had been emotional as it finished its last episode.

Joanna Froggatt, who plays lady's maid Anna Bates, said she was crying by the end of the production. She said, "I just had my own tears, but it developed into everybody in tears by the end of the day, so I think I would have been in absolute pieces if I'd been there for that very last moment."

Meanwhile Dame Maggie Smith, who is busy this year with the upcoming film "The Lady in the Van," revealed that she will relax and watch the show. She said, "I'm going to be lying down. I believe for quite some time. The other thing I will be doing is watching it. I will get the box set and have a good look. I certainly haven't watched anything that I've done. I have seen some of it, but I want to sit down and look at it all."

She added that she would be open to a possible movie spin off. "It would be fun. I'm not sure if the wig will be around, but hopefully I will be. I think the wig is slightly more tired than I am," said Smith.

Along with the press conference, the show held a wrap party for the cast. Lily James, Laura Carmichael, Michelle Dockery, Elizabeth McGovern, Allen Leech, Hugh Bonneville, Lesley Nicol, Jim Carter, Phyllis Logan, Samantha Bond and Sophie McSheran were in attendance.

The first images of the final season have already been revealed and they have created much anticipation. While the series will premiere in the fall in the UK, U.S. audiences will have to wait until January to watch the final season.
