Ian Whyte has been a part of the Game of Thrones team from the very beginning. Initially, he was cast to play a white walker (the very first walker seen on the show from episode one). Since he replaced another actor, he split the credit. In the second season, Whyte came back, this time as Gregor Clegane, again replacing another actor. In seasons three and four, Whyte took on another role that fit his body type, a wildling giant. You see, Whyte is a 7’1″ former basketball player. Being a giant is something that comes natural to him. In seasons three and four, the giant that Whyte played had no real name, but on the set, they called him “Dongo the Doomed” (he was the one shooting giant arrows up to the top of the wall). But Whyte’s big opportunity came in seasons five and six when he took on the role of Wun Wun, the giant everyone knew best. Wun Wun is the big ol’ giant who sacrifices his life to break through the gates of Winterfell, helping Jon Snow reclaim his home.
