First full trailer for Avatar: The Way of Water released

The first full trailer for James Cameron's Avatar sequel has been released, returning viewers to the planet of Pandora nearly 13 years on.

The two-and-a-half-minute teaser for Avatar: The Way Of Water, introduces Jake and Neytiri Sully and their children, more than a decade after the events of the first film.

The new trailer takes viewers below the waves of the ocean filled with fantastic creatures resembling colorful jellyfish, whales, and large-winged fish.

Jake is seen teaching his daughter to hunt with a bow, as she tells him: "Dad, you know I think I am crazy, but I feel her. I hear her heartbeat. She is so close."

He asks: "So what does her heartbeat sound like?" before she replies, "mighty". The Na'vi people native to Pandora are also seen going back into battle with what appear to be humans using advanced technology and weaponized "mech suits". Watch the full trailer below!
