What “box office gross” means here
The ranking measures worldwide nominal theatrical lifetime gross: the reported ticket sales from domestic and international theatrical releases, including recorded rerelease receipts. It is not adjusted for inflation, limited to domestic sales, or a measure of the money a studio keeps after theaters and other costs.

Do not treat gross-to-budget ratios as profit. Box Office Watch notes that listed production budgets exclude marketing, and comparing a film’s gross with its budget does not establish a studio’s net return.
Why different box-office charts disagree
Lifetime totals vary by database, and the gap can be substantial. The Numbers listed Titanic at $2,223,048,786 when its worldwide chart was retrieved October 8, 2026; Box Office Mojo listed $2,264,812,968 on its chart retrieved the same day. For Avatar, the corresponding figures were $2,923,706,026 and $2,923,710,708. Those differences are why this ranking uses Box Office Watch for every row rather than mixing sources or implying that the displayed totals are audited receipts.
Rereleases can also change lifetime grosses. For example, The Numbers’ record for Terminator 2: Judgment Day includes theatrical rerelease entries, illustrating why a film’s reported total is not necessarily fixed at its original release.
Scope: nine narrative features, not every directed theatrical film
This list is limited to Cameron’s nine narrative feature films. The Box Office Watch filmography also includes Billie Eilish: Hit Me Hard and Soft—The Tour (2026), a concert film rather than a narrative feature, so it is excluded rather than folded into this ranking.

A dated milestone for Avatar: The Way of Water
On February 21, 2023, The Walt Disney Company reported that Avatar: The Way of Water had earned $2,243.2 million worldwide to that point and had passed Titanic. That was a dated studio milestone, not a current total; later reporting and database updates can produce different lifetime figures.
