The budgets for Disney's streaming shows are growing to be some of the most expensive in the industry, with the first season of The Mandalorian alone costing $100 million for ten episodes. It was later reported that the shows from Marvel Studios would cost twice as much, with each episode of WandaVision being budgeted at $25 million per episode at the time.
Thus far, from what fans have seen in the WandaVision trailers, this enormous budget hasn't been too apparent, but recent comments from Paul Bettany point to this show having more VFX shots than even Avengers: Endgame.
In an interview with Total Film, Paul Bettany spoke about the scope of WandaVision and its relation to the wider universe of the MCU, saying that “I think it will make everybody look at the Marvel Cinematic Universe in a whole new way." He also claimed that WandaVision has more VFX shots than Avengers: Endgame:
“Marvel has always taken big swings... But we’re a really big swing. There are more VFX shots in WandaVision than we had in Endgame. That’s a big ask.”
WHAT THIS MEANS
Keep in mind that WandaVision will be a six-hour series with nine episodes, while Avengers: Endgame was a three-hour-long movie, so, of course, it makes sense that WandaVision would have more VFX shots than Avengers: Endgame. It just means that Marvel Studios is using every penny of their $200 million budget for WandaVision.
Over a year ago, Marvels Studios VFX producer Jen Underdahl actually put a number to Endgame and said it had 2,698 shots in the movie, with 2,496 of them involving some VFX. This means that WandaVision has at least over 2,496 VFX shots throughout its nine-episode run, which is itself still pretty impressive since there's likely to be a lot of shots that don't involve VFX as half the show will be riffing on straight-forward sitcoms.
It's also likely that most of these VFX shots will be towards the end of WandaVision when the series transits into a more traditional MCU action-packed climax.
