> A good, clean, new 35mm print is very clearly distinguishable from from a 4k projection. Even casually you can see the difference What difference are you referring to? If you're talking about clarity/pixels, the source format is as important as the projection. Academy and super 35 waste a lot of space on the frame. Super 35, which was really common for big time movies a few years ago because you could use spherical lenses, actually requires an intermediate step making it anamorphic for projection... which makes it less clear on the print. The only 35mm source format I would argue provides higher resolution on 35mm than a 4K projector is going to be anamorphic (aka Panavision or 'Scope). It requires no intermediate step before projection. It looks like Nolan is shooting Dark Knight Rises anamorphic and 70mm for the IMAX stuff. Other than resolution, the blacklevels of film are higher and there's weave on film. Plus, unless you only go to high end theaters that take projection seriously, your typical projector jockey at the local AMC can barely get the movie in focus. I once saw Saving Private Ryan projected with no matte. So every time an effects shot came on, the top and the bottom were cropped. Non effects shots had full frame.
