In their respective weeks, those movies dropped 50.3 percent, 59.4 percent, 58.4 percent, and 59.5 percent – which should show you just how amazing a 46.5 percent drop really is (plus, Black Panther made more money in its opening than three out of four of them).
In the last 10 years, Marvel Studios has obviously established a very strong box office reputation, but the truth is that comic book world has never seen anything like Black Panther before.
The Ryan Coogler blockbuster is only the fifth film to make more than $400 million domestically, and at this rate it will probably wind up behind only The Avengers in the rankings.
As perfect proof, one only needs to look at how the second week numbers stack up against the top four domestic earners in the franchise: The Avengers, The Avengers: Age of Ultron, Iron Man 3, and Captain America: Civil War.
