If you had a reasonable budget and about a dozen people to develop a 4K projector over the course of a year, and your goal was not simply to make money but actually to improve the sharpness of cinema presentation, you'd be better served sending those twelve people around the world for a year focussing the existing 2K projectors in every theater they could find.

- last movie I saw happened to be in a small town cinema. We arrived late and had to sit on the second row closer to the screen and you're totally right. Either that or it wasn't 2K projection at all (wich I wouldn't doubt either)Sep 5, 2011
- If I had a group of people committed to making a 4k projector, I would be terribly disappointed if they didn't come to me with a badass 4k projector, but only an improved 2k projector...Sep 5, 2011
- If I had a 2k projector, I'd probably throw it just a tiny bit out of focus to prevent aliasingSep 5, 2011
- 4k is evil to work on and completely unnecessary. Doing GI-Joe at 4k felt like I was fluffing a certain person's ego rather than making a better shot. :/Sep 5, 2011
- Don't develop a new projector chip, develop an autofocus projector lens. Just make it refocus on a pattern before each show.Sep 11, 2011
- To me, the goal of 4k cinema is so you can sit nearer the screen and get a more immersive experience, but with no obvious pixels.Sep 11, 2011
- If you don't want to see pixels, why not project from film?Sep 11, 2011

For the same reason why theatres screen on 35mm rather than 16, or 8...
As a direct answer to your question:
Film has a more limited lifespan. A 4K film will last a lot longer in showings whilst being a very similar resolution to (the grain of) s35 mm film.
Also, I am assuming that once mastering is done it would be far cheaper to copy/download 4K data to the theatres storage systems rather than to make 50,000 prints of the same movie.
Lastly (i am assuming) digital would be far more environmentally friendly than having to make all those prints...Sep 12, 2011
