Watched this for the 3rd time in theaters, 2nd time in 3D IMAX. Not counting probably the 20 times at home. Still enjoyed it. Sequel confirmed. Looking forward to buying a 3D TV next year so I can enjoy these movies (James Cameron has pretty much said it will be a trilogy) in 3D at home.

But not only did director James Cameron always believe that the film would be a hit — he was even planning a sequel during production. “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 says. “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.”
