Excellent opening!
I agree with everyone who said that Paul's death contributed to this big OW numbers. No way to measure it but there's always curiosity especially for a high profile movie/media property like this. Like someone mentioned Glee's rating rose significantly for the tribute episode for their late leading man but after that the ratings went back to its normal low ratings, Michael Jackson's death led to the rise of sales in his past albums as well and strong opening for the concert movie he was not able to finish. It sounds wrong but it's human nature
Nevertheless, had Paul lived on and FF7 opened in its original July 2014 schedule, it would have opened strong as well maybe still over 100M
