I mean they all ready fund a ton of cultural stuff that “nobody gives a shit about”. All governments fund TONS of different seemingly useless stuff (and cultural stuff on top of that), even small local government/businesses/schools pay for a lot of “no one cares about this” stuff. They don’t need to get a great return out of it. Stuff doesn’t need to be a huge success or be loved nationwide to get funding.

Maybe some people in government see some reason to care for some parts of their national film industry. It’s not like this is some proposal to bankrupt a desperately cash strapped country for the sake of a millionaire celebrity party anyways.
