For years I carried a film I couldn't make. It lived as a single image in my head: an unbroken camera flying forward through corridor after corridor, each one dissolving into the next through a portal at its vanishing point, until the last door opened onto the first and the whole thing began again, a loop with no seam, no beginning, no way out. It was too strange to pitch, too expensive to build, too specific to hand to anyone else. So it stayed a dream. But the tools finally caught up to it. The Parasite is that film. Across six worlds a Soviet sanatorium, a coral-choked cathedral, a reactor sealed against the thing behind its door, a container ship rotting from the inside, and the nest where it all begins a man walks into a hospital, collapses, and is caught by a stranger. That small mercy is the whole catastrophe. Only when the loop closes do you understand what you watched: the man was never sick, never a man, but a carrier grown by the nest to walk out and infect the world that made him. The end is the beginning. Kindness is the weapon. There is no origin, because it never stops. Every frame here was built to serve one idea, that the way we move through a story can be the story. The forward flight is the infection's advance; the loop is its immortality. I designed the mechanic, wrote the recursion and used AI as the camera, the crew, and the set I could never have afforded.
