It has been rumored for a while, but now Latino Review is saying that Arnold Schwarzenegger will play the 'bad guy human general' in James Cameron's Avatar 2. Treat this as a rumor for now, as there has not been any official word from 20th Century Fox. Also, it is unknown whether he would just star in the first sequel or the other films as well.
Schwarzenegger previously worked together with Cameron on the "Terminator" movies and True Lies.
Back in August, Fox announced that Cameron had increased the Avatar sequels from two to three. It was also revealed that Cameron had hired screenwriters Josh Friedman, Rick Jaffa & Amanda Silver, and Shane Salerno to collaborate with him on the screenplays for the three films.
The three pictures will be filmed simultaneously with production beginning next year. The release of the first sequel will be in December 2016, with the second to follow in December 2017, and the third a year later.
