It was made for Cinerama ..
.. which I don't think has existed since the 70s. Mostly it is screened in 70 mm, which is not as immersive for the audience.
OTOH the digitized version available on DVD has far better image and audio quality than any celluloid or video version I've ever seen, a really 'live' and contemporary quality. I saw a free-to-air broadcast of it a few weeks ago and was most impressed - even on a home TV screen.
