Entertainment Weekly is reporting that James Cameron had started making plans for a sequel to Avatar during production. The director stated, "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."

Sam Worthington is already signed to do a sequel, and he sent Entertainment Weekly his ideas for a sequel, joking, ""Jake should have abused his avatar and be fat and unfit and demand Neyteri to get him a beer."
