Deadline: 20th Century Fox, Lightstorm Entertainment and Hewlett-Packard have partnered in a five-year agreement to create the next-generation digital experience for the three sequels of the box office giant “Avatar.” As part of the agreement, they will create an entire digital world of “Avatar” off-screen designed to keep the franchise alive before the sequels and as a thread between each one.
