People say this about almost every blockbuster ever made. Films are expensive to make. $175M is not even high end for a blockbuster anymore. Factoring in USD inflation, this is the cheapest Spider-man movie ever.
Yeah Marvel is pro level budgeting. According to Deadline Homecoming cost a third of what ASM2 cost, which seems pretty insane
This Spider-Man cost before P&A a similar amount to other titles in the Marvel Cinematic Universe: $175M. Thats more than a third cheaper than Sonys previous title in the franchise, The Amazing Spider-Man 2 which even with combined theatrical P&A and production costs of $430M saw a profit of $70M-plus after all global TV and home entertainment monies were counted.
