Google Cloud has opened submissions for Agentic Cinema: The Blockbuster Hackathon, an online competition offering $75,000 for AI agents designed around film and entertainment workflows. Entries opened on July 27 and close at 10:00 p.m. GMT+1 on September 7, 2026. Participants must be above the legal age of majority in their country of residence, with some countries and territories excluded under the official rules. The challenge asks developers to build a functional agent or multi-agent system powered by Gemini and Google Cloud Agent Builder, with each project required to integrate a product or Model Context Protocol server from IBM, Grafana, Parallel, ClickHouse or Replit. This is not a competition for AI-generated films; entrants must create a working tool for a media and entertainment process involving filmmakers, screenwriters, studio crews or fans. Potential applications include script processing, video transcription, asset captioning, storyboarding, speech generation, sentiment analysis and production data management. Entrants must provide a URL to a hosted project, a three-minute video demonstrating the agent working, and a public open-source code repository with a complete open-source license. Five partner tracks divide the prize fund, with first-place winners receiving $7,500, second-place winners receiving $4,500 and third-place winners receiving $3,000, accounting for the full $75,000. Judging will consider technological implementation, product design, potential impact and the quality of the idea.
