14. Ben Crompton (Ross/Eddison Tollett)
Having gained some acclaim as a result of his role on Thrones and on BBC Three comedy Pramface, Ben Crompton's small role in Series 8's Into the Dalek disappointed some fans. His character Ross barely lasted any time at all before being exterminated by Dalek antibodies. He did get one of the most talked about scenes from the episode, though, when the Twelfth Doctor tricked him into thinking he'd be alright while actually using his death to get the rest of the group to safety. Not cool, Doctor. On Game of Thrones he plays Eddison Tollett, known as Dolorous Edd due to his gloomy disposition, one of the members of the Night's Watch. He's managed to survive so far, getting through attacks by White Walkers, raids on rebellious watch members and assaults by wildlings, becoming one of Jon Snow's most dependable allies in the process.
