Movies like Avatar: The Way of Water

If you want Avatar: The Way of Water's blend of immersive underwater world-building, family-centered survival stakes, and protagonists mastering hostile environments to protect their loved ones, you'll likely find similar ground in Avatar: Fire and Ash (same director, same thematic DNA), Aquaman and the Lost Kingdom (elaborate aquatic environments as character), and Moana 2 (oceanic wonder plus crew-based protection narrative). There's a moderate chance Avatar: The Last Airbender scratches the elemental mastery and family-bond-under-pressure angle, though the tonal and pacing differences may be steeper than the underwater options.
