(CNN) -- With fans still reeling from last Sunday's Red Wedding episode, "The Rains of Castamere," the third season of "Game of Thrones" comes to a close this weekend, and no one is waiting with more bated breath for that than Nikolaj Coster-Waldau, who plays Jaime Lannister, the Kingslayer on the HBO program. "Even though I've read all the scripts, I wasn't around when they shot all of it," he reminded CNN. "So one of the things that's great about this show is that I can actually watch it and enjoy it, despite knowing what's going to happen." Coster-Waldau, who recently appeared in the Tom Cruise film "Oblivion" and is shooting "The Other Woman," a romantic comedy with Cameron Diaz and Leslie Mann, finds the most interesting aspect of watching "Game of Thrones" is being able to reassess the constantly shifting scales of morality in a world where no one character is completely a hero or a villain (save for perhaps Joffrey?). Daenerys Targaryen, for instance, might be the Mother of Dragons and liberating slaves, "but she's burning down cities! She's killing all these other people!" he laughed. "I'm sure a lot of those guards are just guys with families."
