"Black Panther's second weekend is bigger than Justice League's opening weekend."Yeah, and its not even that close. Black Panther had the #2 second weekend of all time, beating Jurassic World and Avengers by a fair way. $112m was the actual, which is an insane performance. Its now looking fairly likely it'll become the #1 domestic superhero film of all time, may have a shot at #3 dom of all time (above Titanic at $659m).
Its overseas which is the focus now, can the OS performance take it above Civil War, Iron Man 3 or maybe even TLJ? Time will tell! Its 10 day WW total is about $710m, China will add an easy 100m+ to that so its getting there.
