When it hit the box office our family was driving by a theatre in Toronto with the posters up. $5.00 a ticket when normal admission was anywhere from 25 to 75 cents. My dad exclaimed "forget it!" I was 11 then so no argument, mind you it was a high end theatre with the latest ancillaries. I've still not seen it.
Correct Galu, it was 70mm projected in one go, but they still billed it as cinerama - perhaps people were familiar with the name. I still have a big poster... somewhere. We got to see it and got lots of souvenirs (posters, etc) as a friend's dad worked for the uk promoter.
My research shows that Super Panavision 70 was technically compatible and virtually identical to Todd-AO.
Googling Todd-AO reveals it was designed to be:
“a motion picture system that would photograph action in very wide angle ... with one camera ... on one strip of film ... to be projected from a single machine ... on a very large screen ... with a quality so perfect that the audience will be part of the action, not just passive spectators.”
