Without looking at Xev's special sauces (I use the inferior Box Office Mojo, which doesn't do very well with "foreign" numbers).. ..Lol its just a different forum, mojo is pretty meh, they're slow and make mistakes and some data is confusing.
Endgame will probably be able to crawl out another 80 million in the US.
And it needs to make around 92 million elsewhere.
It feels so close, but it'll probably be a crawl over the next few weeks at least...
If I was to bet right now I'd put Endgame about $10-20m short of Avatar, it would be a shame to come so close and fail but whatever happens it was an incredible achievement.
