So was this a box-office flop?
$55 million budget, and they grossed about $95 million. Generally, movies need 2.5x their budgets to break even, so this movie needed 138 milliion, no?
shareIf you really believe they need 2.5x their budget, and if you believe what studios say a given film cost, then sure.
I believe a more realistic viewpoint is that Hollywood exaggerates the costs of movies, in large part to write off more against their taxes than they probably should, but also to fortify the mythology around the entire industry. Much like NBA players heights are exaggerated, it's good for business.
The profit to the studio from the tickets sold was probably about $43 million. But, studios also receive money from corporations and other sponsors for all manner of things. The MCU films get about $100 million per movie from that alone. Challengers likely received nowhere near that much, but it wouldn't be crazy to assume they got $10-15 million for various product placements or shared advertising.
The film likely made the studio a small profit, but there's no way for us to know.
