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.

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.
