I think considering that 3D is doing somewhat well out there, and considering many tv's now come with it whether you want it or not (my set has 3D but I specifically wanted that feature because I'm a 3D fan myself), this was a missed opportunity by the studio to use 3D to create the true curved feel of the Cinerama format.

They could have mapped out the "smilebox" type of screen, but in 3D, requiring the viewer to use their 3D glasses. The movie itself of course would not be in 3D - it would be 2D, just mapped correctly onto the 3D Cinerama "smilebox" screen. Instead of false curves and distorted angles, it would look like you were actually looking at a true Cinerama curved screen. On a larger 3D tv especially (say 46" or anything larger), this would look stunning. It would be like you were literally looking at a curved Cinerama screen inside your set, with the film being displayed in 2D onto the curved screen as originally intended.

Why have a flat 2D smilebox presentation of a format like Cinerama that just begs for a true 3D curved screen, when so many tv sets now have a true 3D mode, and blu-ray supports 3D? They easily could have included a 3D smilebox version and I bet people would have found it stunning to see a real curved "screen" displaying that film.
