Circle-Vision 360° is a film projection technique, refined by The Walt Disney Company, which uses nine projectors for nine large screens arranged in a band on the walls of a cylindrical theater. By using an odd number of screens, with a small space between them, a projector may be placed in each gap, projecting across the space to a screen on the opposite side of the room. The screens and projectors are arranged above the heads of the viewers, and guests stand to view the film.

The films were shot using nine cameras mounted on a special rig. For scenes in cities or on highways, the rig was transported by automobile or by a variety of land carriers. For aerial views, a specially equipped B-25 bomber was used as a camera ship. The nine-camera assembly was mounted in the bomb-bay with a hydraulically-actuated trapeze assembly that was lowered for clear-view 360° filming.

Circle-Vision Theaters were particularly challenging acoustically. There were the normal difficulties with a cylindrical theater shape, which reflects sounds made within the circle back toward the middle. This was addressed using wall and ceiling absorption as well as overhead loudspeaker placement. The projectors were noisy and the lenses protruded into the theater between the screens. Due to image quality concerns there could be no glass in front of the lenses. MLA developed specially designed attenuating bellows that provided a seal around the lenses to prevent the intrusion of projector noise into the theaters.
