There were reports that Schwarzenegger who worked with Cameron's 'Terminator' franchise, will reunite with the director on the billion dollar franchise to play a "bad guy human general" but 20th Century Fox has denied that the actor was approached for a role, said the Hollywood Reporter.
Cameron is bringing three sequels to 'Avatar'. The director has hired screenwriters Josh Friedman of 'War of the Worlds' and Shane Salerno of 'Salinger' fame to collaborate with him on the screenplays for the three films.
The three pictures will be filmed simultaneously with production beginning next year.
