Watch the new Avatar: Fire and Ash trailer, which stars Sam Worthington as Jake Sully as he and his family facing an epic war against the Ash People, a newly revealed Na'vi clan hardened by tragedy and led by Varang.
The trailer delves deeply into the origins of the Ash People, displays new environments and creatures on Pandora, and teases a complex conflict that involves both old human enemies and internal Na'vi divisions. ~Alexandra Heilbron
