This is going to be the plot of a Bruckheimer/Emmerich co-production, is it? A team of scientists needs to travel into the heart of a volcano to find the lost city of Lithium, but one of them is actually a spy for a foreign power that will try to kill everyone else to prevent the secret to get out, only to be thwarted by the lone survivor, a man who was recently divorced by his wife and just wants to see his children again. He finds another (female) survivor, and together they defeat the spy mastermind and are evacuated by the US Military mere seconds before the volcano erupts.
It certainly couldn't be any worse or more idiotic than the scripts for probably every Hollywood natural disaster movie: The Day After Tomorrow, The Core, Deep Impact, Armageddon, etc.
Yeah, it wouldn't need ChatGPT and it wouldn't take a week - my initial post pretty much came to my mind fully formed because it's just every action movie trope of any 90's/00's Blockbuster. I can probably write a 90-Minute script over the course of a week if I write only during toilet breaks, the main issue is "Will there be $40M in the budget to blow up an actual Volcano?"
