Circle-Vision 360° is a film technique, refined by the Walt Disney Company, that uses nine cameras for nine huge screens arranged in a circle. The cameras are usually mounted on top of an automobile for scenes through cities and highways, while films such as The Timekeeper use a static camera and many CGI effects. The first film was America the Beautiful (1955 version) in the Circarama theater, which would eventually become Circle-Vision theater in 1967.
It is used for a few attractions at Disney theme parks, such as Epcot's O Canada!, Reflections of China, and Disneyland's defunct America the Beautiful (1967 version), Wonders of China, and American Journeys, which were housed in the Circle-Vision theater in Tomorrowland.
By using an odd number of screens, and a small space between them, a projector may be placed in each gap, projecting across space to a screen. The screens and projectors are arranged above head level, and hand bars may be provided for viewers to hold or to lean against while standing and viewing the film.
An early development (1900) of this method using ten cameras was called Cinéorama.
Circlorama  had started in London in 1963 using eleven cameras.

A system substantially similar is in use at the site of the Terracotta Army exhibit at Xian, China. The narrator of Wonders of China is the famous Chinese actor Keye Luke (1904-1991), most remembered for his role as Master Po in the television program "Kung Fu".
