Pri GoT nejde o to, že by tvorcom neodklepli 3 filmy. Nápad s filmami mal finančné základy, kedy si mysleli, že na filmy skôr získajú peniaze, viď článok Polygonu:

"The plan was originally pitched, according to the story, back in 2012 while the series’ third season was filming. The idea was that making the episodes into movies instead might help grant them the budget they needed to finish off the story on the grand scale that George R.R. Martin’s description of the events demanded.

As it turns out, that wouldn’t be necessary. In the intervening years, Game of Thrones has grown from major hit to one of the biggest franchises in the world. The popularity helped Benioff and Weiss convince HBO to fund the final six episodes with a massive — for TV — budget of more than $15 million an episode."
