The production team consisted of 15 people: the director, five actors (Paul Mazursky, Frank Silvera, Kenneth Harp, Steve Coit, and Virginia Leith), five crew members (including Kubrick's first wife, Toba Metz) and three Mexican laborers who transported the film equipment around California's San Gabriel Mountains, where the film was shot. Due to budget limitations, Kubrick improvised in the use of his equipment. To create fog, Kubrick used a crop sprayer, but the cast and crew was nearly asphyxiated because the machinery still contained the insecticide used for its agricultural work. For tracking shots, Paul Mazursky recalled how Kubrick came up with a novel substitute: "There was no dolly track, just a baby carriage to move the camera", he told an interviewer.
