What Mark Kennedy said.
... Because of the way that the media writes about films, only a very small number of people ever get any credit or acknowledgement of their role in the making of the film. That's totally understandable…the public has little interest in reading too much about any one movie, usually, and we just want one or two faces so that we can say, "oh, that's the author of the movie", and then we move on to the next thing. But don't let that fool you into thinking that one or two people are responsible for making a movie great. In my experience, it takes a great creative team to generate a successful movie, and an atmosphere where everyone can challenge each other is a safe supportive way. It's easy to say and hard to do, but when you can get that kind of environment to work, it seems like you can accomplish anything.
Mark has had a long career in animation, and knows whereof he speaks.
Many people who plus the movies that become blockbusters, who make our fine, entertainment conglomerates and the execs who run them even richer than they already are often go unnoticed, often get laid off from the job when it's completed, and may or may not jump onto another project and continue their careers.
In Cartoonland, it's not just writers and directors who make the features successful. It's board artists. And designers. And animators. And modelers, riggers, surfacers and lighters who make the eighty-seven minutes of bright illusion into a satisfying whole.
Lots of times that gets overlooked; fortunately, creators like Mr. Kennedy know who's responsible for the magic. And are happy to tell us what's what.
