ARIA Interactive Cinema is an Artificial Intelligence (AI) agent platform that turns film and content Intellectual Property (IP) into a living storyworld shaped by a shared audience. Streaming, short-form video, and games expand access and control, but rarely create a moment when people in one room hear one another, influence a narrative, and carry that experience forward. In ARIA, the character is the interface. Audience speech, choices, and reactions are interpreted within creator-defined story rules. The Character Behavior Model (CBM) converts collective intent into dialogue, emotion, expression, movement, relationship state, and scene behavior. ARIA Production Intelligence structures shots, scenes, assets, metadata, and rights; optional Character-to-Video (C2V) recombines them or generates controlled connective sequences. Each screening can continue through follow-on episodes and connected screens as Playable Intellectual Property. Our vision is to connect the shared presence streaming cannot provide and the isolation games leave unresolved through a continuous online-offline cinematic experience.
