Well, according to Variety, HBO will spend $15 million an episode for the sure-to-be-fucking-epic final season of Game of Thrones.
For comparison, Game of Thrones cost ~only~ around $10 million per episode in the most recent seasons.
Now, TO BE FAIR, it's also been reported by Vanity Fair that each of the six episodes set for Season 8 may actually be "movie-long" — basically, 80 minutes or longer.
The only question I have left though is: Does this mean we'll get a little (no, A LOT) more DIREWOLF action in Season 8?
