A totally different class of production of course, but I really enjoyed The White Queen last year and your mention of Cecily Neville reminds me of a scene where Elizabeth Woodville stands up to her and says you may not like that your son married me, but my mother had FOURTEEN children and I've already proven that I can make boy babies, so NER NER.
(you could make a good drinking game out of the times she went on about her family's fabled fertility)
