10 Actors Who Will Never Escape Their Doctor Who Roles

6. Jenna Coleman

OK, so this one isn't entirely fair, since she hasn't even left yet, but it's safe to assume that Jenna Coleman has now gone so far across the line that she'll be eternally typecast as the impossible girl. In fact, the line is like a dot to her. Still, it could be a lot worse. She's been lucky enough to travel with not one but two dynamic Doctors (and let's not forget that she's also met them all), and she'll always be remembered as the coveted companion who got to star in the franchise's feature-length 50th anniversary extravangazathon. Not too shabby. Oh, and she got to travel the globe on last year's World Tour, too, and her return in the upcoming series will officially put her in good stead as NuWho's reigning longest serving sidekick. No wonder she keeps changing her mind about leaving.
