From what I can see, the advertising push was pretty heavy for this film. I'd be very surprised if it was only 50mil. I'd guess it needs about $575mil total at a minimum. But who knows.
Oh it’s almost assuredly more than 100 million for marketing.
The trouble is the industry rule always was a 2.5x modifier for a film production to break even when all is said and counted. On the generous assumption end even. There’s even circumstances it’s as low as 2.0x. The industry rule has been completely misinterpreted to try and estimate all sorts of things it doesn’t do, like guesstimate marketing spend. Marketing spend is almost always more than 50% of the budget.
Marketing includes post theatrical spend, you market for streaming or PVOD. Trying to carve out only box office as the single revenue source has merely been a tactic to make Disney productions appear less profitable than they historically have been. But it also buries the true costs too (post theatrical marketing spend, profit sharing, participation / residuals).
2.5X tracks very well, so generally the production at 600M Box office will make Disney 50 million and at 700M 100-ish.
