A video in which Jim explains that, “the thing that people need to keep very strongly in mind is that this is not an animated film.” So just to recap: yes, Avatar has 100% digitally animated characters in it; no, it’s not animation; why, because Cameron says so.
Regardless of how Cameron and Fox want to frame their marketing campaign for the film, I have little doubt that Avatar will be viewed by history as an animated feature, right there along with Zemeckis’s mo-cap works. Granted, none of these are particularly exemplary examples of animated films, but they do represent the beginning of a new animated technique. (It is a testament to how rapidly animation is evolving as an art that we can no longer even identify what is an animated technique.)
