Spencer Wilding has featured in many big-name films and television shows, including the Harry Potter series and Game of Thrones, but is not easily recognised. This is largely because he is typically employed as a "monster actor," being one of the most prolific in the industry at the moment. In Doctor Who, Spencer has played such fearsome foes as Skaldak the Ice Warrior and the Minotaur, both against Matt Smiths Doctor. But he has also made a fleeting appearance in the Marvel Cinematic Universe. Guardians Of The Galaxy fans may remember the scene in which the guard at the Kyln has a sneaky listen to Star-Lord's mixtape - yeah, that's him.
