Here's hoping that Endgame dethrones Avatar, just to spite James Cameron
I know that the title of this post sounds petty but then so are the many subtle and direct insults that Cameron has heaped on Marvel and other comic book movies.
It would be a bit of cosmic justice if Avengers: Endgame ended up making more (adjusted for inflation) than Avatar.
Here's hoping. That would be extra icing on the cake!
