Castle Black was really disgusting.
The set decorator, Richard Roberts, did his best when creating the residence of the Night’s Watch. According to his idea, the castle was supposed to look “dirty, grungy, cold, and as disgusting as possible.”
In order to create this atmosphere, he asked to hang raw meat and bring in real pigs. The actors say that not only did the castle look greasy, but it was actually greasy in real life. “It smelled foul and looked foul but that’s how it should be, so we’re happy,” Roberts concluded. However, we are not aware of whether the actors had the same opinion.
Bonus 1: Sean Bean played football with his own head.
The actor who played the role of Ned Stark is very used to death scenes. And he relates to every scene with a good sense of humor.
That’s why he found a good use for the model of his own head — he used it to play football with the set team. This kind of attitude inspires viewers to not worry so much about another death of their beloved character.
