Fox is trying what it claims is a first for take-home movies with an upcoming iTunes Extras Special Edition version of Avatar ($20 pre-order, iTunes). The James Cameron action movie will let viewers see and control simultaneous views of 17 key scenes the movie that include the completed picture, the rough-computer generated framing, and the live motion capture. Green Screen X-ray will also let viewers selectively see the raw live action side of the content just by dragging the "X-ray" over parts of the scene.
