Cinerama was and still is the most important and impacting widescreen movie system ever created. Nothing equals, not even IMAX the wonderful sensation that Cinerama caused on its audiences,
I think the latest Cinerama is a movie theater with a digital screen equipped with 16K micro LEDs arranged on a curved surface for exclusive use of images, modeled after the Sphere built in Las Vegas. You should be able to easily create this shot using Apple Vision Pro. Therefore, I would like them to build a new Cinerama theater in Hollywood and then expand it internationally.
I was a kid when Cinerama 1st came out...The Roller Coaster ads on T.V. & newspapers had me hooked & wanting to see this new format..The 1st Cinerama film with the Coaster ad did a 2 year run in just one theater. People could not get enough of this marvel...
You forgot to mention the first ever plot film made using the three projectors Cinerama system. It was THE WONDERFUL WORLD OF THE BROTHERS GRIMM. It was made before How the West Was Won but it was shown some time after HTWWW was presented.
