Well, it’s only noon, so take this with a big grain of salt. But sales have been way outpacing Endgame’s comparable hours. The 90k gap in CGV PS has already fallen to 57k, and will clearly narrow much further before likely expanding back at night. If Frozen II can bank enough advantage in the afternoon and early night, I believe there is a legit shot at beating Endgame’s Sat here. Unless I’ve completely blanking on some crazy holiday, that would be the biggest Hollywood Sat all time, and the biggest Hollywood single day admits all time.
Of course, it must be stressed that even finishing fairly close to Endgame would be staggering, and at least being the 2nd largest HW single day admissions seems fairly likely (again, unless I’m missing some holiday that spiked 1.5M+ — but I doubt it).
Btw, maybe @imbruglia, @Olive, @ZeeSoh, or someone else could help me out here: what are the highest single day admissions all time without restricting to Hollywood? Is it Endgame’s 1.663 Sat?
