Once the people who owned the 70mm projectors found out that Tarantino was releasing 100 70mm prints and none of the theaters had projectors anymore - everything is digital to keep distribution costs down- the price to buy a 70mm projector skyrocketed. Never mind that it took 5 used projectors to get parts to make 3 functioning projectors. The 70mm print barely fits on the platter. Personally I really do not like seeing scratches on film prints. I really like digitally projected films and unless I can see a "wet gate" print I am not interested in seeing film projection.
Theaters pay studios around 90% of their receipts for the first week (although this is negotiated by each theater chain. That is why the popcorn is so expensive - they are making a lot more money selling candy and popcorn than they are making showing the movie. If the theaters could get concerts, sporting events and other large venue events on their big screens they might come close to wanting to stay in business. Imagine a football game in 4k resolution on a giant screen!
I just remember what happened with the music and film industries saying that the cassette tapes, VCRs, CDs and then DVDs and so on would kill their business and then it turned out to be a huge money maker. How can the MPAA be so wrong so much of the time and have no major studio notice. Are they giving away yachts to studio execs?
