The first four in the back row Left to Right are Daisy, Ruby, Edward, and Rose. The two ends of the seated row are Georgina and James (see picture below).
My recent reading of Ivy Compton Burnett's Manservant and Maidservant made me think more than once about the fabulous Upstairs Downstairs. They aren't all that related, but there were hints here and there. I was trolling around the Interwebs when I stumbled on this story and photo from the Evening Standard. It was great to see the picture below from 2007 with some of the cast members. I think the most amazing thing is how well Jean Marsh (number 8) looks. March played Rose on the show and was one of the show's creators along with Eileen Atkins. Not only does she look really good full stop, but she is actually the oldest person in the photo. If I look that good at 73 I will be very happy. And if she has had work done she has a very good plastic surgeon. (I also just noticed at IMDB that she did an episode of Love Boat. That would be fascinating to see.)
I have heard some rumors online that they are going to remake UD with Jean Marsh's involvement. Since the 1970s' sets and film quality are a bit lacking by today's standards, I would love to see that. But I am not sure how I feel about other actors playing any of the roles. But then again, who am I kidding. This would be great to see.
