URL copied Posters of Avatar, Avengers Endgame It was a rather eventful weekend for James Cameron's Avatar as it reclaimed its box office crown by being the highest grossing film worldwide. The film dethroned Avengers Endgame, which took Avatar's achievement briefly in 2019. Celebrating the milestone, Marvel Studio's shared a creative on Twitter and congratulated Disney for the same. "Congratulations to @JimCameron @JonLandau , and ALL of Na'vi Nation for reclaiming the box office crown! We love you 3000." While congratulations are in order and makers of both the films are exchanging warm notes of appreciation, MArvel and Disney fans are at a war. The fans of two franchises have taken to Twitter to prove their film is better.Â
