Soundtrack thoughts;
Temple of Doom is such a D&D movie. A party of three PCs has at best tenuous reasons for being involved in the plot, and after social encounters go nowhere because the DM REALLY wants them to go in the dungeon, they basically spend the rest of the movie there. The arch-villain's motivations are a nebulous take over <strike>Malatra</strike> India/by being so evil that you don't start asking why NOT let Indians run their own country instead of Brits/wearing an awesome hat.
@Leucrotta I've been doing this with movies and TV series too, deciding what is happening in the role playing game that leads to the game world plot that we see
@chimerror My pet theory about Alien as a TTRPG is that Gorman's player was going for power armor (so he didn't make someone who'd be particularly tough out of armor, with skills for stuff that wasn't power armor combating, but he did sink a batch of character creation points into commissioned rank needed to have the armor legally).
