The Tumblr picture to your right was one that a friend sent me and it makes me a little sad. The screencap comes from the 50th anniversary special "The Day of the Doctor" where Clara Oswald is taken into the UNIT Black Archives and passes a board decorated with known associates of The Doctor. Fun as it might be to imagine, as the poster did, that the small picture of a young man featured was that of Peeta Mellark from the Hunger Games in a neat bit of crossover humor, it's actually one of the least discussed companions in Doctor Who history, Ben Jackson.
Admittedly, the resemblance between Hunger Games actor Josh Hutcherson and Ben's actor Michael Craze is actually sort of striking. That said, Ben remains obscure even for fairly well-informed fans. It's a little odd considering some of the landmarks that Craze was present for in the show's history such as the first regeneration, the birth of the Cyberman, one of the last purely historical adventures and more.
Ben and his friend Polly Wright were the final companions of the First Doctor, and joined him on his last three television adventures after the departure of Dodo Chaplet. He was a sailor from Cockney with a solid working-class background. He and Polly chanced upon The Doctor when he was trying to thwart the sentient supercomputer WOTAN. He was a man of action who was an indispensable asset to The Doctor in the fight, and he and Polly made an effective team from the second they stumbled into the Tardis trying to return a key to The Doctor as he left London following WOTAN's defeat.More »
