Last night at the Hero Complex Film Festival, filmmaker James Cameron was on hand to discuss his seminal action/sci-fi masterpieces The Terminator and Terminator 2: Judgment Day. The course of conversation took a turn though to Cameron’s new hopefully equally seminal-in-the-making action/sci-fi trilogy: Avatar. Cameron hired three writers to collaborate on each of the three upcoming sequels (Josh Friedman, Rick Jaffa & Amanda Silver and Shane Salerno), in an effort to get all the films ready to be shot back-to-back-to-back later this year. Last night, Cameron delved into the process behind writing these three sequels simultaneously. For Cameron’s revealing thoughts on the matter and how television gave him the idea in the first place, hit the jump.
