Avatar — $2.92 billion
James Cameron's effects-driven sci-fi epic briefly lost the top spot to Avengers: Endgame in 2019, then reclaimed it after a 2021 re-release in Chinese theaters pushed its total back into first place. Cameron first conceived the project in 1994 but delayed production for over a decade until visual-effects technology could catch up to his vision, eventually spending roughly $237 million to build Pandora on screen.[1]
