Hell Grind: Rebuilding Our Biggest Fight Scene from Scratch

We open-sourced Hell Grind — our AI feature film — and rebuilt one of its biggest fight scenes from scratch. Every prompt is free below. 👉 All assets, prompts, and skills: https://higgsfield.ai/s/hell-grind-breakdown-higgsfieldai-rdbpqy 💵$1,000,000 Contest: https://higgsfield.ai/s/hell-grind-breakdown-higgsfieldai-Cfwtju Hell Grind was the first AI feature film, made in 14 days and premiered at Cannes. Now the whole project is open — every prompt, every asset, every iteration — and in this video I rebuild the samurai battle scene shot by shot with Claude and Seedance inside Higgsfield. You'll see the failed generations, what actually broke, and the exact fixes: how to fake an army of a thousand, write camera moves in meters, build bullet-time, and why telling AI what NOT to do backfires every time. Plus we're announcing a $1,000,000 AI film contest — judged by Oscar-nominated cinematographer Phedon Papamichael and Pixar co-founder Ed Catmull. ⏱️ TIMESTAMPS 00:00 Intro 00:27 Open-sourced Project 00:41 Win a $1,000,000 Contest! 01:29 The scene we're rebuilding 03:33 Setting Up The Claude skill that writes the best prompts! 04:08 Shot 1 — The opening oner (3 iterations) 09:57 Shot 2 — Faking an army of 1,000 12:30 Shot 3 — The transformation 13:51 Shot 4 — Bullet-time first strike 15:55 The Final Edit Links 💬 Discord: https://discord.gg/higgsfield 🐦 Twitter / X: https://x.com/higgsfield 📸 Instagram: https://www.instagram.com/higgsfield.ai
