Spielberg's advice for the aspiring USC filmmakers was, well, straight out of a disaster film script:
"Eventually going to be an implosion — or a big meltdown. There's going to be an implosion where three or four or maybe even a half-dozen megabudget movies are going to go crashing into the ground, and that's going to change the paradigm."
TechCrunch picked up the story as well, with one of their suggested remedies being not making "s**tty films". The problem with that, of course, is that no movie studio ever owns up about any of its films being junk, unless their name is Troma and they had no shame to begin with (and even then it hasn't helped). And so we have strategies like $50 mega-ticket showings being explored as a way for the studios to recoup.
No, not sustainable.
