Not returning is actress Lily James, who has went on to leading lady status in recent years and this summer starred in Mamma Mia!
Remarkably, given the massive size of the cast and the post-Downton Abbey success some of them have went on to, the show’s original principal cast will be returning for the movie.
Although she will be missed, there are also a bunch of new additions to the cast, including the talented Imelda Staunton.
According to Lily James though, her absence makes sense story-wise.
