Incredible greed and arrogance from the big six behemoth, which probably means most non-multiplex cinemas simply can't show The Last Jedi. Disney are demanding 65% of ticket revenue AND the movie must play in the biggest hall for five weeks ... or they'll demand 70%!
It's not the first time Disney have messed cinemas around - they had to back down from a reduced cinema release window for Alice in Wonderland.
This is what happens with concentration of ownership (one of Chomsky and Herrman's five filters in their propaganda model by the way), which is why anti-trust laws once forced Hollywood to split up its vertically integrated studios (before deregulation commenced under Reagan in 1980).
