Hmm … curious. Live action squeezed (for eventual expansion) and animation at academy size for … what?

I found this on Wikipedia, which indicates no widescreen version was ever released. Why then Superscope? Some funny aspect ratios as widescreen on the cheap? Or is this some Alice-In-Wonderland-induced hallucination?

"I wanted a special show just like Cinerama plays today … I had Fantasia set for a wide screen. I had dimensional sound … To get that wide screen I had the projector running sideways … I had the double frame. But I didn’t get to building my cameras or my projectors because the money problem came in … The compromise was that it finally went out standard with dimensional sound. I think if I’d had the money and I could have gone ahead I’d have a really sensational show at that time."
Walt Disney on the widescreen release in 1956.[91]
