I think the biggest advantage of Hollywood [both US and centralized], is their bigger budget that leads to better quality, and recognizable/good actors. With generative AI, good quality doesn't need as big of a budget. As for the actors, they aren't as big now as they were before. People have different interests, with the youth opting for YT and Tiktok versus regular movies. The acting will depend on the software. I can also see makers guiding their software by recording a specific move that they want, and have the software use it.
