Behind the scenes: How Avatar 2 redefines film technology

In addition to its economic and critical success, the 2009 film Avatar made history thanks to its ground-breaking use of motion capture and computer graphics. With Avatar 2, director James Cameron has once again built and utilised new technology. Some behind-the-scenes footage has been released by the filmmakers. The underwater motion capture technique used in Avatar 2's numerous underwater sequences was developed by Cameron and his business Lightstorm Entertainment. In the past, underwater motion capture required suspending performers using cables in order to record their facial expressions and other important moments. The water was then created using CGI.
