Season 7 of Game of Thrones is good news for everyone because the show is amazing and addicting. It's better news for the show's main stars because they'll be making a butt-ton of money off the upcoming episodes. Deadline is reporting that some key actors will be making at least $500,000 per episode, which is $200,000 more than they're getting for each season 6 show.
There are a few caveats to this new round of contract negotiations. For starters, there's no guarantee that the actors will survive to see the end of the season or season 8, which hasn't been confirmed but will very likely happen.
The pay raise only concerns Kit Harington, Peter Dinklage, Lena Headey, Emilia Clarke, and Nikolaj Coster-Waldau. Other actors (like Maisie Williams) have apparently not yet ironed out their contracts. Read into that what you will you fanatic theorists.
