I think the issue is ... trying to create a 2D texture map, that would look correct if projected onto an actual Cinerama screen?
Sitting in a good seat at Cinerama, the image doesn't look compressed ...
That's right, and such a projection is correct in both directions.
However, my last (this) approximation is also inaccurate in that the projection lines from the curved screen to the flat screen (see that top-view diagram) are parallel, as if to an infinite focus. The focus should be somewhere in the audience. That ups the level of manual labor. (I was trying shortcuts for quick mock-ups, but each time I'd think about it and come back to throw more work into it. Somebody stop me!)
Of course, the best projection would be to fill it upto the widescreen (16:9) area while maximizing the normal-proportioned center to it's cinemascope (2.35x1) boundary. Or, if putting it in a cinerama theatre setting, do it proportionally smaller to fit.
Are you still thinking of trying a stereoscopic representation of a 3D cinerama screen? With or without the theater? :)

Heck, while you're at it, you can turn it into a real game ... Imagine the multiplayer possibilities, as you and your friends debate the best plan of action against the "noobs" behind you, kicking your seat and throwing popcorn ... maybe I've gone too far @_@
Well, maybe just a little. :D
But we have to give Oldfan, and all of us for that matter, the original experience of 2001. To that end, I was thinking of additional theatre-centric ambience (no popcorn):
* curtains opening & closing at beginning & end
* dimming & lighting (the theater) at movie start, intermission, movie exit
* theater reflection-lightness in sync with movie lightness (?)
* the slight concert-hall-sized hollow/echo sound
Sorry to make even more work for ... whoever wants to pick up this gauntlet. :)
