"The Avatar sequels-Avatar 2, Avatar 3, and Avatar 4-could be the first movies to use the high frame rate system 4K, 3D system. Douglas Trumball's system delivers 120 frames per second. He told The Hollywood Reporter that he has talked with Avatar producer Jon Landau about viewing the short film UTOFOG, which is a showcase for Trumbull's patented process, dubbed MAGI, for capturing and displaying images at 120 frames per second in 4K and 3D on giant screens using conventional digital projectors. Trumball said that James Cameron has admired his earlier high frame rate system but didn't know if Cameron was interested in the new system. But THR reported that Trumball indicated that he has talked with directors 'very interested' in the technology. 'This will be driven by the directors. If directors like Cameron, J.J. Abrams, Peter Jackson want this, then I think we'll start getting some traction,' he said. The system helps to deliver a more fluid experience than normal. 'It delivers extreme fluidity of motion and amazing clarity with no strobing, no double flickering and a viewing experience that far exceeds conventional movie quality,' said Trumbull."
It has been confirmed years before that Avatar will be made into a trilogy, which means there will be two more movies coming up in the future. This is after the success of the first movie, which Director James Cameron spent 12 years in making. The first movie was released in 2009, and the sequel is expected to be released in theaters between 2014 and 2016.
Lead roles Sam Worthington said in an interview that the director has talked to him about undergoing some training for underwater filming. This obviously tells us that the sequel will be featuring more of Pandora's waters, giving off an exciting and a very interesting thrill to all fans.
When IFC asked lead actress Zoe Saldana about what she knows about the sequel, she said: "I don't know [when the sequel will start filming] but I'm waiting. My bags are still packed," this exchange happened during the Film Independent Spirit Awards red carpet.
In an earlier interview with IFC, Director James Cameron said: "I want people to feel that same sense of excitement about that world, you know the fictional Na'vi people and I want them to feel that excitement of discovery of a new world that they're going to see things that they haven't imagined. All that sort of the perk package of the first movie is still going to be there. And the themes will be there and be played out in a way that I think people can accept." He further added, "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. 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."
As lifted from IFC, Cameron has said in a statement to THR that: "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."
