Factoring in marketing costs and the theaters taking their cut of the profits, Megalopolis would need to make at least $300 million to break even. I think it's safe to say that's not happening.
It would have been THE worst opening for a $100 million movie ever, had it not been for Pluto Nash's horriffic opening 22 years ago.
Maybe if the trailer didn’t tell you how great and misunderstood Coppola and his works have been and how stupid people were for panning them when they came out, more people would have been compelled to see it. Not that it was pretentious, just arrogant to say hey come watch this this sure fire masterpiece. Also it looks like politics mixed with Inception so maybe too much for people to bother right now? Having said all that I would like to see it, just don’t need to go to the theater for this one.
