And it doesn't use a crappy made slap of capaldis head in a random body!
Game of Thrones star, Maisie Williams (Arya) was spotted filming for Doctor Who with Peter Capaldi in a forest in Wales. Signed on for a two party, Maisie is rumored to jump from a Viking themed episode to a 17th Century one.
No sign of her filming with Clara, but it's early days yet. We can't wait for these episodes!
