James Cameron's planned "Avatar" movie trilogy is becoming a quadrilogy.
Josh Friedman (War of the Worlds), Shane Salerno (Savages) and Rick Jaffa and Amanda Silver (Rise of the Planets of the Apes) have been hired to collaborate with the director to write three follow-ups to Cameron's 2009 sci-fi hit "Avatar," 20th Century Fox announced recently.
The original currently stands as the USA's all-time box-office champ with a take of $760m.
The first sequel to Avatar, which followed a space marine (Sam Worthington) going native with a race of blue alien Na'vi on the moon Pandora, will begin production next year and will film simultaneously with the two other sequels.
"Avatar 2" is due out in December 2016, with "Avatar 3" coming in December 2017 and "Avatar 4" tentatively releasing December 2018.Jim Gianopulos, head of Fox Films, said that everyone at the studio had "no higher priority, and can feel no greater joy, than enabling Jim to continue and expand his vision of the world of 'Avatar.'"
In 2010, Cameron said that there would be two sequels that would feature "self-contained stories that also fulfill a greater story arc."
"We will not back off the throttle of 'Avatar's' visual and emotional horse-power," he said.
Last year, Sigourney Weaver said she will appear in the sequel, despite her character dying in the first installment.
