What is movie-gen?

movie-gen is a working pipeline for making short AI generated films, roughly five to twelve minutes long with dozens of shots, while keeping the same characters and voices consistent across the whole film. It stitches together several AI services: Seedance for video, Nano Banana Pro for images, Sonilo for music, all accessed through a tool called Higgsfield, plus ElevenLabs for character voices, Gemini for automatically checking audio and image quality, and the video tool ffmpeg to assemble everything into a finished file. The process moves through clear stages. First you generate character portraits to keep faces consistent, then a starting image for each scene using those portraits as a reference, then cast and record voices for the script. Before spending money on full video generation, the whole film is put together cheaply as an animatic, meaning still images paired with the recorded voice lines, so you can catch story and pacing problems early. Only after that do the expensive video clips get generated, followed by adding music and sound, assembling everything with ffmpeg, and reviewing a rough cut to decide what still needs fixing. About ten films have already been made this way, including an eleven minute comedy called The Long Game, which is included in the repository as a full worked example with its scripts and iteration history. The project is explicitly designed to be driven by Claude Code rather than run by hand. A person mainly needs accounts with Higgsfield and ElevenLabs, then Claude Code reads the included playbook document, asks what kind of movie is wanted, installs tools, and drives most of the pipeline, leaving the human to review previews and give notes.
