These were the toughest ones to find clues for, since neither one can be found on IMDB, YouTube, Google, or any of the other places I searched. When you google Maisie's name, however, you get a bunch of hits for Maizie Williams, a singer for an old pop group called Boney M. But of course THAT Maizie Williams was not our Arya, hence the clue that one player was NOT a boney pop singer.
Here's our Arya:
Sophie Turner was just as hard to find. No, she's not the middle-aged actress who played in the DR. WHO episode. She's not any of the other Sophie Turners that google will turn up, either. I thought about trying to cobble together some kind of "not Sophie Tucker" clue, but finally gave it up as a bad idea, and in the end I never did drop a hint for Sophie.
(That's not the best picture, I know. Sorry, didn't have a lot to choose from. I am sure better pictures of both Maisie and Sophie will be forthcoming).
You guys cannot possibly know how hard these roles were to cast. I've viewed dozens of readings for both girls. Sweet kids, some with great looks, all of them bright and eager and enthusiastic... but good child actors are rare. Maisie brought Arya alive in a way that none of the other kids could match, right from the first. Sophie read two scenes; the scene with Arya on the kingsroad, and a much later one when Joff is forcing her to look at the heads on the walls. Two very different sides of the character. She knocked 'em both out of the park.
I think you're going to love these girls. I know I do.
