Because the resolution criteria are somewhat subjective, I will not be trading in this market.
Basically trying to answer this as a reasonable person would:
I'm imagining a movie that looks like a live-action film; cartoons don't count. It should clearly depict the story of OpenAI's firing-Sama drama, etc.
I think it's okay if the script was written by a human who fed it to a model that produced the movie. It would be nice, of course, if the script were mostly generated by an LLM, but that part is doable with the right prompt engineering using current technology, so it shouldn't be part of the resolution criteria.
I will disregard any AI-generated movie that appears to have been made specifically to trigger a payout for this market. This criterion, too, is subjective.
If an AI takes over the world and enslaves all of us, then before I report to my job at the paperclip factory I will try to resolve this to "YES" on the assumption that such an AI is capable of making a movie and just has an unusual reward function.
