"You're absolutely right! When Obi-Wan told me about my father's death, he probably meant that the person he knew my father as is dead, since your personality and appearance have changed drastically since then. I'm glad we could clear up this misunderstanding!"
I unironically think nic cage would kill it in a parody of this idea. Randomly gets and loses a prosthetic finger between scenes. The background changes slightly randomly. And instead of a full script he's given the equivalent of a prompt for each scene and just has to "figure it out"
I've been convinced that scripts for several big budget films over the last few years have already been written by LLMs. Scripts for things like The Marvels and the last 2 Mission Impossible films (just the first couple that immediately come to mind) are stream-of-consciousness slop with inconsistent logic, jargon that makes no god damn sense, side characters and tangents that come out of nowhere and do nothing, and really forced 'member berries, because as Jay from RLM puts it; "nostalgia is the new cocaine!"
Nah, they're just the results of a film industry who's spent decades running on the principle that the best qualification for getting into the industry is the willingness to kiss the asses of the people that were already there.
A bunch of first draft song lyrics, too. I know a lot of idea generation for songs has gone that way. Most songs in popular genres sit in the same basic scaffold so it's been easy for them to say "give me a (4, 6, or 8) line verse talking about such and such. Then give me a chorus that reinforces that idea. Ok, how do we move the second verse forward? Give me a couple of chorus variations. Big emotional high point bridge". Then they go through it with a scalpel to make it coherent and keep it flowing. Then they do another 10, varying the number of lines, the number of verses, or remove the bridge or whatever.
