Chris: From a non-technical viewpoint, the interesting points raised are fairly esoteric. Illustration is essentially a solitary pursuit, where the individual’s ethos and creativity are what drives the art to its end result. Animation, on the other hand, is normally the very essence of collaboration. The design, direction, story boarding, techniques and technology combine in various, almost alchemic parts to create the final piece. So the jump from solitary creator to happy collaborator is an interesting one.
Some illustrators are natural storytellers, whereas others are formidable image makers. Understanding the individual strengths and weaknesses of each creative is an important strength and one where a great producer can make all the difference. On top of that, there are the other intricacies of production, which are often led by the quirks of the style chosen; CGI, stop motion, cell animation or after effects? Or a mixture of these. Usually only trial and error or experience will tell. So, all illustrators will need to be able to work in an animated environment, that is without question, but will all animators be able to become animation directors, that is a question of ambition and desire, it can only be answered by the individual.
