Cinerama is a widescreen process that originally projected images simultaneously from three synchronized 35mm projectors onto a huge, deeply curved screen, subtending 146-degrees of arc. Subtending refers to the pathways of the projected images from the synchronized projectors onto the curved screen overlapping each other at one point. The trademarked process was marketed by the Cinerama corporation. It was the first of several novel processes introduced during the 1950s when the movie industry was reacting to competition from television. Cinerama was presented to the public as a theatrical event, with reserved seating and printed programs, and audience members often dressed in their best attire for the evening.

Michael Todd was an American theater and film producer, celebrated for his 1956 Around the World in 80 Days, which won an Academy Award for Best Picture. Actress Elizabeth Taylor was his third wife. Todd was the third of Taylor's seven husbands, and the only one whom Taylor did not divorce. Todd died in a private plane accident a year after their marriage. He was the driving force behind the development of the eponymous Todd-AO widescreen film format.
