According to Corpse, Marvel/DC films typically have poor legs in Japan (barring a few exceptions) with multipliers averaging around 4. So $26-27 million I'd guess.
No way. Corpse has it at $6.6M, a great result given the exchange rate. It could maybe reach $7 million but $9 million would be over a billion yen and there's no way it did that.
FF7 had Golden Week (and there was competition, local movies though), AOU won't have any holidays. By the time Obon comes around in August, it will have fallen down in the rankings.
For a US population of 259.92 million in 1993. Making as much of an impression proportionally would require 106 million tickets sold today which would be a gross of 866 million when taking the average ticket price.
But...are you not aware that The Avengers still hold the record for the sunday gross between 6 and 7 pm when looking only at tickets sold to 16 year olds ?
With current exchange rates if it does the same as TA1 it will get to $29M. But OS performances suggest it will drop and its release date isn't as good so I would bet on $20-25M..
