Avatar premieres in London

Set on the fictional word of Pandora, this 3D epic tells the story of wheelchair bound ex-marine Jake Sully, played by Australian Sam Worthington. Given the opportunity to control a cloned alien body with his mind, Sully uses his new alien vehicle to infiltrate the native Na'vi people in an attempt to assist a corporation extract a priceless mineral.

Originally conceived in 1995, Cameron had to wait over ten years for film making technology to develop enough to allow him to fulfill his dream of creating the digital masterpiece. Avatar blends live action and computer animation.

Cameron broke his own record of making the world's most expensive film. Avatar's budget, well in excess of 2.5 million dollars, trumps Titanic, which cost 200 million at the time.
