Star Tours utilized hydraulic motion base cabins featuring six degrees of freedom, including the ability to move 35 degrees in the X-Y-Z plane. The simulator was patented as Advanced Technology Leisure Application Simulator (ATLAS), originally designed by Rediffusion Simulation in Sussex, England, now owned by Thales Training & Simulation (ex-Thomson-CSF). The Rediffusion 'Leisure' simulator was originally developed for a much simpler show in Canada called "Tour of the Universe", where it featured a single entrance/exit door in the rear of the cabin and a video projector. The film was front-projected onto the screen from a 70 mm film projector located beneath the cockpit barrier. The Disneyland original had four simulators, while the Tokyo Disneyland, Disneyland Paris, and Disney's Hollywood Studios versions each had six motion bases.
