James Cameron already had the biggest movie ever with Titanic. After 12 years, he topped himself when Avatar broke the two biggest box office records. The film took so long to make because the necessary technology wasn't available when Cameron thought of the idea, and it showed. The movie went on to win three Oscars for cinematography, art direction, and visual effects, with still rising revenues approaching $800 million domestically and $2.6 billion worldwide. Oh, and he has everybody in Hollywood jocking his IMAX 3D steez.
