For the casual viewer who wants to see this in CINERAMA, the possible closest way to do so is to purchase the How The West Was Won Special Edition on Blu-Ray disc. On Disc 2 of the set there is a "SmileBox" version of the film.The SmileBox process converts the film as if it was shown on a curved CINERAMA screen and the SmileBox process was used in the documentary Cinerama Adventure, available as part of the How The West Was Won Special Edition on standard DVD and Blu-Ray.At this time, the SmileBox version of How The West Was Won is not available on standard edition DVD.
