Re: How The West Was Won - Blu ray
An interesting article on the Cinerama theater.
Several major differences from the original Cinerama installations, though.
1.
The original booth layout was either 3 or 4 separate booths, one each for Able Baker and Charlie projectors. In the theaters purpose built for Cinerama, thr Baker booth also contained the audio dubber and a conventional 35mm projector for the breakdown reel. In theaters that were retrofitted, the dubber and the 35mm projector for the breakdown reel were usually located in the original projection booth located way up on the back wall. The audio console was out in the auditorium. The 3 projectors were required to be positioned exactly level with the center of the screen and perfectly centered with it's respective screen panel.
2.
Large reels were used as platters were not yet invented in 1953. Using reels minimized the possibility of film damage. since mis-threaded platters are responsible for most of the physical film damage seen in todays theaters. Reel size was also the reason for the intermission in the original Cinerama features, even though they were 2 hours or less long.
3.
The original Cinerama screens were composed of many many individual strips or louvers, each one facing forward. This was done to avoid the image on the sides of the screen from washing out the image on the opposite side. I may be wrong, but I believe that the Hollywood Cinerama does not have this type of screen. Here is a picture of the remains of a louvered screen in an older installation:

And a better picture part way down the story:

In comparison, the Cooper Cinerama theaters had the original style louvered screens right till the day they were torn down. I believe the Seattle Cinerama also has a louvered screen.
Also, the Hollywood Cinerama has a Cinerama screens sized at 32' x86' which is the modified single strip Cinerama AR . Compare that to the Coopers at 35' x 105', or the Seattle Cinerama at 30' x 90'.
