I can't resist putting these images in dialogue. Are the two esteemed actresses thinking of each other in their grey flat-ironed wigs, or is this a subliminal cry for a sequel to the sapphic wonders of The Hours? As Christian so correctly observed on Twitter, Nicole is never going to let a grey hair near her scalp. But she died in The Hours so she can't be in the sequel anyway.
This twinned image was fun to discuss on Twitter but after the fact it reminded me of an earlier conversation with Anne Thompson and Kyle Buchanan about why there are so many aged lady villains in YA adaptations. My contention is that it's their ageist way of playing both sides. So many stories about young girls that pay lipservice to "girlpower" are, just like stories centered on men and boys, still scared of the power and agency of (adult) women; these prejudices are deeply ingrained.
