Movies like Avatar

If you want Avatar's specific blend of environmental catastrophe, indigenous resistance, and family-centered survival stakes, you're most likely to find it in the sequels themselves—Fire and Ash deepens the same Na'vi-versus-exploitation conflict across new landscapes, while Project Hail Mary and Mission Stardust both explore the moral reckoning when humans discover an alien ecosystem deserves protection over profit. For the visual spectacle and underdog-scale conflict without the environmental conscience, Battleship delivers comparable action scope, though it trades thematic weight for pure military spectacle. The Matrix and the Soviet-era entries (12 To The Moon, the unnamed Cold War Venus film) probably scratch different itches—groundbreaking action language versus tactile worldbuilding—but none quite align on all four axes the way the Avatar sequels do.
