I first bought Cinerama "The Seven Wonders Of The World" I liked it so much that I bought this one too! I may eventually buy all of them. The restoration is perfect and the "Smilebox" format does a good job stretching the screen so as to duplicate the huge three screen Cinerama effect.
This bluray plays well on all of my blueray machines. It must be without region, but I am not an expert on this subject. I live in the USA and it plays perfectly.
