Mark Mayerson writes a pretty good rebuttal to the idea that the animators that worked on James Cameron’s Avatar were shortchanged by the film’s placement as a live-action feature:
“I’ve written extensively on how fragmented the process of making an animated film is and how so many of the acting decisions are made before the animator starts work. The character designs, the storyboard and the voice performance all make acting decisions that constrain the animator’s interpretation. There is no question that motion capture is yet another constraint, probably larger than all the others. To insist that Avatar is an animated film is to marginalize animators even more than they are in what are generally considered animated films. Is this the direction we want things to go? Better to agree with James Cameron and focus our attention on films where animators create, not enhance, performances.”
