I know I keep saying it, but the uniqueness of this event is the main thing impressing me at how well it's doing. It's Taylor Swift in her record breaking era, so of course this was going to be huge either way. But people forget that tickets went at a price of $19.89 per adult and $13.13 per child. No rewards program such as A-List are allowed to be used, so everyone who is going WANTS to pay that money.
I also haven't even mentioned the other very unique thing about this which is that it did NOT do Thursday previews (which could've inflated the Friday gross on what is practically a 3 hour showing) and going forward during it's run, it is only being shown on Thursday, Friday, Saturday, and Sundays, which was a decision made so that fans can experience the movie, as intended, which is singing loudly in a packed theater with other fans instead of being the only one in the theater. Also, the first showing of opening weekend Friday isn't until 6PM. Unheard of.
Even with all of those unique factors that this filmed concert have (extremely high ticket prices, limited showings, no rewards programs, etc), box office analysts still can't figure out where it will fall this weekend with BoxOffice.com showing a range of anywhere between $105-$145M and Variety surmising it may pass $150M in it's opening weekend, again WITHOUT Thursday in play and most of Friday even out of play, it still is looking at these huge numbers.
If the film does open on the higher end of expectations, it will very likely be the highest grossing Friday-Sunday of the year (taking out Thursday previews). Barbie brought in $22M on Thursday and opened to $162M so an opening of $140M or higher would put it as the highest Fri-Sun.
