Box-office sensation "Avatar" is back with a third movie this December, teasing epic family drama and stunning new creatures in the first trailer.

“Avatar” and “The Way of Water” both grossed over $2 billion at the worldwide box office, making them two of the most commercially successful films in history. If “Fire and Ash” follows suit, “Avatar” will be the only franchise to have three films cross the $2 billion threshold.

Fire and Ash teaser poster introduces Varang, an intriguing new character fans are about to meet soon. Oona Chaplin, who is best known for playing Talisa Maegyr in Game of Thrones, makes her debut in Pandora as the new villain.
