I'm genuinely shocked there's no show or movie made with AI yet. If you expect to put in "good movie five stars Oscar bait" and get two hours of footage, yeah, no. Obviously no. But real movies are made from small pieces. Existing public tech is enough to really half-ass your way around needing actors or locations. (Or Blender skills.)
But no - it's always 'look how neat this looks!' and not 'here is a story I've been wanting to tell.'
