I feel like audiences are far more interested in all the behind-the-scenes "making of" stuff these days. When I was a kid, movies were a lot more mysterious in how they got made, which all added to the immersion of the film viewing experience, separating it from real life.
Nowadays, .namely thanks to the internet, all the nuts and bolts of what goes into making a film is freely available to the general public, so if the general public is interested in the politics of diversity (and large parts of it is), then the "magic of the movies" no longer works to keep it insulated as this other imaginary realm, untouched by real-world concerns.
