And though Game Of Thrones actor Thor Björnsson, who plays the formidable Mountain, can't give away any spoilers, he knows who he would like to see last standing. 

Speaking with Daily Mail Australia on Tuesday, the 27-year-old said his loyalty to House Lannister goes beyond his fictional role by Cersei's side and into reality.
