'Avatar' Prequel Will Come After 'Avatar 2' and '3,' Says James Cameron

An 'Avatar' prequel would be the fourth in the film series, according to director James Cameron. But Cameron says he's not working on the Avatar prequel yet.

Sigourney Weaver mades waves when she announced that James Cameron plans to shoot three Avatar sequels as a single massive undertaking. However, producer Jon Landau recently clarified that the Avatar 4 will be filmed separate from its peers (assuming it is made at all).
Cameron has since revealed that a fourth Avatar movie (again, should it happen) would take on the form of a prequel to his original box office record-obliterating 3D sci-fi epic. Meanwhile, Landau’s playing down speculation that Cameron intends to spend the rest of his days making Avatar films – by suggesting that Cameron’s long-awaited Battle Angel/Battle Angel Alita adaptation will finally come to fruition once the Avatar trilogy has been finished.
