About the film
Cinerama Adventure is a 2002 documentary about the history of the Cinerama widescreen film process. It tells the story of the widescreen process' evolution, from a primitive multi-screen pyramid process to a Vitarama format that played a big part in World War II, to the three-screen panoramic process it eventually became. The film includes interviews with surviving cast and crew who personally worked on the Cinerama films, plus vintage interviews with late creator Fred Waller.
