James Cameron 'not planning Avatar trilogy'

James Cameron has revealed that the upcoming Avatar sequels will not round out a trilogy.

The Titanic director stated that he is writing two separate scripts for Avatar 2 and Avatar 3 respectively, promising that the films will each be able to stand alone, according to Fox News.

"We're shooting two films back-to-back, so I'm writing two scripts, not one, which will complete a free-film story arc - not really a trilogy, but just an overall character arc so I'm pretty excited about that," Cameron said.

Cameron went on to state that while he feels the pressure to write quality sequels, he is not letting himself become overly stressed.

"There's always an expectation," the 56-year-old said. "I had to deal with that after The Terminator back in 1984. All of a sudden I had a big hit movie and it was, 'What are you doing next?' But my job is take the audience on a journey and entertain them. The second I am sitting down writing, I just go to Pandora. The characters have their own lives."

Ioan Gruffudd recently described Cameron as having a "Jekyll and Hyde" personality, claiming that while the director can be difficult on set, he is perfectly charming off set.

Cameron predicted in April that there will be a 100% take-up of 3D technology in cinemas over the next five years, stating that he also hopes to see an expansion of the technology into the home.

The two Avatar sequels are scheduled to be released in December 2014 and 2015 respectively.
