10 Actors Who Should Be The Next Doctor Who Companion
If Jenna-Louise Coleman does leave Doctor Who this Christmas, who should replace her?

10. Hannah Murray
Hannah Murray is, to put it simply, an actress that the camera loves. She's not exactly what you might call a conventional beauty, but she has an ethereal quality which makes her incredibly engaging. She is soft, gentle, and somehow otherworldly. Casting her as a companion could upon up a world of possibilities for the show. If they wanted to, they could have her be another contemporary Earth companion, and that would be fine. But a much better use of her talents would undoubtedly be to make her the first alien companion on Doctor Who in a good long while. She would make an amazing alien. Her star is on the rise, with critically acclaimed performances as the deeply troubled, spacey Cassie on Skins, and now as the young Wildling woman Gilly that Sam is infatuated with on Game of Thrones. So she's becoming more and more recognizable, but still maintains something of the unknown quality that Doctor Who showrunners tend to look for in their companions.
