Joan Crawford in ‘Paid’ has a certain fierce quality that can be applied to Arya, and Veronica Lake has an ethereal quality that can be applied to Dany. Of course, these are only suggestions :)

(I’m assuming you’re the same anon as before) Joan in Paid could totally work. I was also thinking maybe Sylvia Sidney in some of her roles? (she doesn’t look much like book!Arya and I’m probably thinking about her because she bears a resemblance to Maisie. Still, even if she doesn’t work for Arya I’d still like to use Sylvia for somebody, she just has a great face). I’ve already casted Veronica Lake as Cersei and I’d rather not do repeats. I’m starting to warming up to the idea of another actress for Dany but like…this particular actress I’m thinking of has one of the saddest stories ever and I’m not sure if I want to deal with the implications.
