Your Handy Doctor Who / Game of Thrones Actor Crossover Guide
Half the fun of watching Doctor Who and Game of Thrones is spotting the actors and actresses* who appear in both. Given that both are filmed mainly in the UK and the one requires a steady supply of guest stars whilst the other has an endless list of characters to depict, it's hardly surprising to see so many TV thesps with a part in each. Helpfully, the Internet Movie Database makes it easy to track them all down.
