The $200 million science fiction film stars Sigourney Weaver, Giovanni Ribisi, Zoe Saldana and Michelle Rodriguez.
Cameron is shooting the film using a new 3D process and will feature a blend of live-action photography and virtual photorealistic production techniques invented by his team. The film will also feature six computer-generated actors known as "synthespians".
Avatar is expected to be released in 2009.
