Avatar is getting a re-release in China, which can be seen reclaiming the title of all-time box office champion over Avengers: Endgame. James Cameron's 2009 science fiction / fantasy is a cultural phenomenon that has garnered critical acclaim and has become the highest grossing film of all time, surpassing Cameron's previous box office champion Titanic. The movies are splitting at the top of the all-time list at less than 10 million, which is a very small number when you realize that both movies have grossed over 7 2.7 billion in total.
