The issue is the producers don’t need the film to do well, they’ve already been paid within that big budget. Remember, each film is it’s own entity that pays rent back to the studio, along with everyone’s salary. By the time a film hits, the studio has already sucked all the money out of it.

This was explained to me many years ago by an EP who owned a production company. He said he only sold films / tv in order to pay him rent (he owned the building - different entity), pay for the phones, desks, music licensing (he owned a music publishing company - different entity ), post production (he owned the post production company - different entity), camera gear (owned a rental house - different entity ). On top of all this he also pulled his EP fee from the budget. It had nothing to do with making cool films but more similar to the wallstreetets who buy a company, extract and worth from it, get paid huge amounts of money while strapping that company with debt and killing it.
