Season 8 of Game of Thrones is shaping up to be its most expensive yet, with each of its final episodes costing HBO at least $15 million each, Variety reported Thursday. That number does not include the price of re-shoots and additional VFX effects. In total, the network may spend well over $90 million on this one season. By comparison, the $15 million-per-episode budget will blow away Netflix’s production costs on The Crown, with its $10 million per episode budget. In Season 1 of the series, show co-creators David Benioff and D.B. Weiss’s budget was too small to show battles in full. There will only be six episodes in Season 8, but each will be feature-length, making season 7’s 80-minute finale look short. The season will premiere in late 2018 or early 2019.
