I don't know...I watched Alice In Wonderland, not filmed for 3D but 3dified or whatever they call it.

It did actually work for me for that film because it created the feel of one of those paper theatre things (what we had before television).

The real problem with it was the shape of the frame which tended to break the illusion.

If the shots were composed to stop characters and other significant objects from being cropped by the frame it would be sustainable story telling element (like colour and sound).

Directors will either have to learn a new compositional language for making films in 3D or drop the oblong screen altogether and make films to be projected on giant concave discs.

I'd watch PT+SE3D out of interest but not until George restores the OUT2D.
