Agreed. Not long after seeing Staunton in HP V, we saw her playing a fairy in Maleficent. She was so cute in that role! Stunning.
Another good example is Frances Sternhagen, who played the immenently horrible "Bunny MacDugal," the mother of Kyle McLachlin in "Sex and the City" as well as the absolutely adorable Willie Ray Johnson in "The Closer." Two moms who couldn't be any more different. Outstanding actress.
