Campbell has been more of an influence on genre fiction than Hollywood. Genre writers obsess about characterisation in a way that screen writers - at least the ones who get regular work - clearly don't.
I used to know a screen writer, and he described Hollywood writing as a theme park ride you watch on a screen. There are standard scenes that every action movie is supposed to have, usually delivered in a standard order, sometimes with standard dialog. There are optional scenes from the Generic Hollywood Scene Library Sorted By Genre that writers can add as needed. The rest is CGI, costumes, and camera moves.
And it's this way because it's what the middle of the bell curve pays for. Anything too clever or original or interesting or challenging may win awards and/or critical praise, but it's not what The Average Movie Ticket Buyer wants.
To add: the original research is pretty much useless, as others have pointed out. That doesn't mean someone who actually understands the industry couldn't codify the tropes and cliches and produce a Plot and Character Machine that generated commercially valuable output. There are quite a few steps from that to generating a filmable script, but even a relatively simple outliner that hit the spot would have real value.
