With you writing this, I don't think you understand how financing in movie business works.
First off, the movie is falling hard behind predictions and may not even break even. The reason is that movies cost a lot more than initially reported because of the massive marketing campaign. So if a movie like JL ends up with "only" as you say, $700 mil it ends up with having a bunch of people fired. The fact that movie opened $70 mil less than BvS is incredibly worrying which means that in following weeks studio will earn even less. Bulk of money comes from first week, no comic book movie earns more per week with time, money always slowly drops with each week. On top of that, there are contracts with movie theaters which say that in first few weeks (depends on each movie) studio earns bigger percentage of ticket sales, as weeks go by that percentage goes down. Translation, it's looking really bad.
Also, quoting Brazil is laughable. Warner Brothers earns a lot less from foreign markets than they do from domestic. They flopped hard.
