Awsome!!! But if we were to look at the money and how much it was worth at different times the highest grossing film is Gone with the Wind (just a little funish fact for you all).
But Gone with the Wind is only the highest grossing movie adjusted for inflation. On the box office alone, Avengers: Endgame wins. If so, then Avatar is still ahead of Avengers, due to the film being bought out of cinemas in home dvd's or something...
