Painstakingly researched, this documentary on the origins, life, and ultimate death of Cinerama, is a time capsule of the fifties and sixties in addition to providing an engrossing history of the process itself. Nothing in the history of motion pictures had the worldwide impact that Cinerama did. It became a weapon in the cold war between the U.S. and Soviet Union. It sparked the widescreen-stereophonic sound-full color revolution in the movies and we still benefit from its innovations fifty years after it premiered. Fans of movie technology will probably wish that the documentary ran a few hours longer.
