AVATAR 2

 "I've had a storyline in mind from the start - there are even scenes in Avatar that I kept in because they lead to the sequel," Cameron said. "It just makes sense to think of it as a two or three film arc, in terms of the business plan. The CG plants and trees and creatures and the musculo-skeletal rigging of the main characters - that all takes an enormous amount of time to create. It'd be a waste not to use it again."Cameron has said in a statement to THR: "In the second and third films, which will be self contained stories that also fulfill a greater story arc, we will not back off the throttle of Avatar's visual and emotional horsepower, and will continue to explore its themes and characters, which touched the hearts of audiences in all cultures around the world. I'm looking forward to returning to Pandora, a world where our imaginations can run wild."Cameron has also hinted that the heroes will venture to some of Polyphemus's other moons in the film. He also confirmed that Avatar 2 will explore the Na'vi culture more than Avatar.On April 20, 2010 Cameron confirmed that Avatar 2 will explore the oceans of Pandora. He also confirmed that Avatar 2 will contain more volcanoes, when prompted by an interviewer.Three days later, it was confirmed that Avatar 2 will take place several years after the events of the original film.Before the original film was released, James Cameron talked about turning Avatar into a trilogy of films that would follow for sure Neytiri and later after the film's release Jake Sully as well. Not long after, James Cameron announced that he is in the process of working on the film. The director also went on to say that the film will most likely not be called "Avatar 2", since Jake is no longer an avatar at the end of the first movie, but rather a Na'vi.  He claims that he plans to once again do the impossible by having a much shorter production time, and for the sequel to be much cheaper than the original. Avatar 2 may be shot in a higher frame rate than the original, which is shot at 24 fps. The sequel may be shot at 48 fps, 60 fps or an even higher frame rate.
James Cameron also confirmed that the sequels would be filmed back-to-back: “I am in the process of writing the next two ‘Avatar’ films now. We are planning to shoot them together and [edit them in post-production] together, and we will probably release them not quite back to back, but about a year apart.” Sigourney Weaver, who recently also dropped hints about a return for her character after a tragic death in the first film, stated that Cameron will begin filming on the second Avatar film next year, and will film the second and third films back-to-back.
