I love celebrating the birthdays of the Firefly cast members, and I think from now on I’m going to celebrate the birthdays of the cast of Game of Thrones as well, since I’m just so darn obsessed with the show. I’ve also been featuring a lot of talented young actors in the Celebrity Birthdays of the Day recently, so here’s another one to add to the list! Maisie Williams plays Arya Stark on the HBO series Game of Thrones, and she’s currently one of my favourite characters. The role is her first, which is pretty surprising given how well she plays it. In addition to acting, Williams loves to dance, and has studied musical theatre, ballet, tap, street, freestyle dance, as well as gymnastics. She’s set to appear in the upcoming TV series The Secret of Crickley Hall. Maisie Williams turns 15 today.
