Because the equipment and lead actors were only available for a short window, Primal Legacy had to be filmed quickly. The production ran on long indoor summer days, with fans and air conditioning turned off whenever sound was rolling.
There were late wraps, missed sleep, weather problems, location issues, injuries, and at least one scene that had to be reshot. The exhaustion was real, and the film depended on people continuing to show up.
Despite the pressure, the shoot was completed. The original notes give special credit to production assistant Will Arland for staying deeply committed through the process.
