The Platform is a 2019 Spanish science fiction-horror film directed by Galder Gaztelu-Urrutia. The film is set in a large, tower-style "Vertical Self-Management Center". Its residents, who are switched every 30 days between its many floors, are fed via a platform which, initially filled with food at the top floor, gradually descends through the tower's levels, each level getting only the leftovers from the previous ones.
