We already knew that Gwendoline (Brienne of Tarth) and Miltos (Syrio Forel) are part of the Star Wars cast next year, but apparently Jessica Henwick will play a role in Star Wars. She's the actress who will play Nymeria Sand in the next season of GoT. A strange casting, methinks. She kind of does not look like a Dornish character (I can live with that), or Oberyn Martell's daughter (that's the hard part).
I have to admit that I like getting my two favorite stories crossing like this but I am also worried that whenever I see Gwen or Miltos on screen in Episode VII I'll be seeing Brienne of Tarth and Syrio Forel.
