The first “Avatar” film came out in 2009.

The movie quickly became the top-grossing film of all time.

James Cameron announced two sequels in the works soon after.

They were supposed to be released in 2014 and 2015.

However, his plans soon evolved.

Two sequels became four sequels and years went by without news.

On Wednesday, the trailer for the sequel was unveiled at CinemaCon.

The title of the sequel will be “Avatar: The Water of Water.”

The film is expected to be released in theaters on December 16.
